I have inserted the code for my mobile site a couple of weeks ago, and it's not showing up in almost all of my tests. The only browser It's working on is Chrome on Android (tested on Galaxy S2). It's not showing up on iPhones, tested both Safari and Chrome on several different devices.
The site is http://m.radicalislam.org
I've looked at this article, and couldn't find any applicable solution

My first step into debugging this issue would be to set the option in Adsense to show a backup ad of a solid colour e.g. Blue or something obvious. This will give you a clue as to whether there is an issue in displaying anything from Google, or if it is an issue specifically with Google serving you adverts.
If the blue colour doesn't show, that might be a good thing, as it could just mean there is an issue with your code (maybe a conflict with all the page speed stuff you've got going on?).
If it does show, then that means Google isn't serving you ads. There's a number of reasons as to why that may be: https://support.google.com/adsense/bin/answer.py?hl=en-GB&answer=75764&topic=2453404&parent=23384&rd=1

I am currently testing my Web Application with different devices and for most of them everything works as intended. Sadly with my IPhone and Safari i am experiencing a weird issue, that it does a Preflight Options Request, when its the same origin. To my Knowledge this is not required. Sadly the Options fails. When testing with Chrome on the same device everything worked. I also tested Safari on a different Iphone and it worked there.
Now the really confusing part is, when clicking on a link to the website in Discord for example with safari it works aswell without doing a Options.
I know that in a "perfekt" World the Options should not fail, but that is another struggle when i was deploying the app. Currently frontend runs under https://example.com and the API under https://example.com/api. I am a absolute beginner with CORS and i am quite confused why this error happens. Another problem is that i cant really use devtools on the iphone to have a exact error message. I can only see the Options in the nginx logs and then the missing follow up request.

I cloned your repo inside codesandbox and found the problem.

You are loading big images to the front end. Each of your images is more than 2mb in size.
First of all you should compress the images and ideally make really small
Then google the term lazy-loading and implement that in your application

My website is deployed on AWS Beanstalk server. on 27 July images were uploaded that were showing. but Today I saw images have vanished, not being displayed. While newly uploaded images are being displayed fine.
What can be the reason? Can anyone help me?
One reason could be due to the fact that your EB instance runs in an Auto Scaling Group.
This means that it can be terminated and launched at any time without your involvement. This can happen due to scaling events, AZ re-balancing, or some aws hardware failures.
Thus its generally not recommended to store any data (e.g. images) on the instances. For that its better to use external storage systems, such as S3 or EFS.
The other reason could be the re-deployment of your application version. If you had sorted the images in your app's current working folder, the redeployment would simply remove it, and replace it with a new one.

I have hosted my Prestashop at Fastdomain server it's like the 4th year, the website is stable and working fine till 3 days ago where my email inbox got full of spam and more than 300K requests on the site causing the site to go down.
I activated the basic protection from Sitelock provided from Fastdomain Cpanel, it worked fine for two days and the site is down again cuz of another strike.
Fastdomain support tried to fix it but no instant method they said the problem is caused due to script overuse in send to friend module, even though this module is an original PrestaShop module, and they said the website will "recover" in few hours.
any comment or thoughts? how t respond to such attack!?
my website is elektrojo.com and am using the up to date version
This appears to be a common problem. Not only is it taking your site down, it may be being used to spam others, which has the risk of getting your domain blacklisted.
In that thread was linked an updated version of the module supporting a CAPTCHA, along with a similar modification for product reviews. It seems to be for PrestaShop 1.5 and 1.6.
If you have some kind of a "backend" which you can update modules on, you should also do that.
Another suggestion is to use fail2ban to detect repeated attempts to access this feature and block it. You may not have the necessary access to do that, but if not, your hosts should be able to.
Failing that, you should remove the sendtoafriend code (ensure the files are actually gone from their original location) until you have found a way to harden it, since it's being abused to take your site down.

Well, it would seem that Google only provide support for Cloud Platform through here, which seems a bit odd, as I've tried to report a bug via their ticketing system only to have it closed with a forward to the Google Product forums, which then got me sent to the slightly-useless Support tab within Cloud Platform itself as there's no forum for Cloud Platform (srsly?), which states "Google engineers monitor and answer questions via Stack Overflow." You'd think they'd have a bloody bug tracker…
Anyway, this is what I submitted via the ticketing system. I'm expecting this to get closed pretty quickly as off-topic, but maybe one of you lot knows where their bloody bug tracking stuff actually is. I can't for a minute believe that they don't have one! >.<

Original bug report:
I have discovered a bug in the Google Developers Console (https://console.developers.google.com) regarding the Cloud Platform. When accepting an invitation from another developer to add a project to your console with a Google Apps for Business account which does not yet have any projects created against it (IE, it is a new account), the invitation request process throws the error "You have no more apps available to accept this invitation".
If the user then creates an app against their account directly, then initiates the invitation process, the invitation is accepted as expected, and the project is added to the account as normal. The directly-created project can now be removed, and future invitations work as normal. If all projects are then removed from the apps account, the error "You have no more apps available to accept this invitation." returns again until such time a directly-created project is added.

As I said, I'm expecting this to get closed pretty quickly, so if anyone knows where Google's Developers Console bugs should actually be submitted, I'd appreciate it if you could let me know before closing it, as I would expect this post to come up in searches for this bug, and a pointer in the right direction on where to go for support would be of help to me and anyone who comes across this post.
Cheers.
