"Error loading documents" in Firebase Database

I'm experiencing error when trying to access Database menu item within Firebase console.
It's a new Database with literally couple records of data but screen keep spinning for ages and then returns message "Error loading documents". In the same time I'm able to access Authentication menu item without any problem.
Note: I'm using MacBook Pro with Catalina 10.15.4 and Safari browser 13.1
It looks like it's a Firewall which is blocking my access to Database section within Firebase Console. Since I'm working on the corporate Mac I don't have control over it.
Workaround that works for me: use alternative private device ie. Mobile Phone.
Disabling the Add-Block fixed mine
For me, the problem was Safari. I was able to access the data programmatically but not via the web UI. Also, Safari worked well for the first few days I used it. I found that when I switched to Brave, I could see all my documents in the console.
On safari it doesn't work. I had to switch browser to Firefox!
Since last Firebase update it doesn't work on Safari anymore, don't know why I tried everything (Ad-block, firewall, ...). Even on mobile.
You have to use another browser to access your firestore docs...
April 16, 2021 : issue fixed, works again on Safari
I had the same problem and I was using windows Microsoft edge, I was using adblocker extension and I turned it off, but it didn't work. Then I opened the console on a chrome browser on a physical device and it worked!
I was trying to access the console in my work laptop with a vpn running in the background. Turn off that vpn and refresh console page. You should be able to see all your documents now.

Responsive design error in Drupal

I have a responsible theme in Drupal and when visiting my site on a mobile device I get a uncomplete view that is deformed. (In the beginning the mobile version worked)
When visiting the site on a mobile device, the site recognises the advice and makes the switch to the mobile site, BUT then I see that the mobile website is displayed like the this: red = mobile site, white = void
How it is at the moment
The idea is that the entire screen is red. :)
I used a different theme = same problem.
I uploaded a new version of Drupal = same problem.
Can you please help me :)
try using the default theme built into drupal 7. Make the theme "Seven" as the default and see if that resolves your issue. If that still doesn't solve your issue, try clearing your cache in drupal via admin > config > performance
If that still persists, try turning off cache on that page completely.
If all else fails install Drupal 7 with NO modules enabled and see what you get. Then turn on each module on one at a time and see how that goes.

Drupal site only shows text

I have a drupal 7 site which has been working greatly until now, but now it just show only text on front and back-end also. I tried to clear the cache and change appearance theme but didn't fix it. I tried to monitor in chrome, by refreshing and monitor Network and Console windows and found in /sites/default/files/ most jpg and png files are not found. But no one has touched the site until we found out it is broken.
Check your Drupal log and your webserver logs. Probably you have problem with file permissions.

Drupal 7 site loads very slow

We have a simple CMS site in drupal 7. The site was loading fine. From the last couple of weeks site loads very slow. It takes more than 10 mins to load front end and admin side pages. We cleared cache and increased memory_limit, but nothing seems to be working.
Hmm, sounds to me like it's database related.

DNN 7 Can No Longer Edit Page

One of my DNN 7 sites has lost its ability to edit any of the pages. It now alway displays the Modules, Edit and Pages menu regardless if admin is logged in or not. When I try to edit a page, a window appears and then quickly goes away. There is nothing of use in the event log and I have tried different skins with no luck. I have another DNN website on the same computer and it works fine.
I have found that I am losing permissions to ToggleUserMode after I recompile a custom module that I'm developing has been installed on a test page and then recompiled in debug mode.
I'm wondering if this can be related to the fact that when I install DNN I blank out the default installation option of creating a dotnetnuke application. I leave that option blank and create the installation in the root of my website.
P.S I tried the amended module tag suggested on SO without any luck.
I finally figured this out. I had originally bound www.example.com to my default website but later created a new site for www.example.com. Apparently most of the requests were going to my new site, but the request for authorization for page editing was going to my old site which resulted in the 401 error. I rebooted my computer and disabled my default website and all is well.
