how to retrieve LogCat data after use Log.d(); statement as we get logcat information earlier - logcat

I have just used Log.d(); statement to debug my app and for this I created a filter configuration. I got it working so that it shows the feedback.
But Now I deleted this Log.d(); from my app. But I can't access the Logcat Information as I got earlier. It's not an error. I just want to get my Logcat as I used before Log.d(); statement.
Would anyone tell me how !!!!

Update to 3.9.16 failing before it starts

I'm running Joomla 3.9.15. I'm trying to update to 3.9.16. PHP is 7.3.15.
I have tried updating from the home page and under components. I have also tried to update by uploading the patch file. In either case, Joomla reports a 500 error before even starting.
The akeeba backup before update is enabled but I disabled it and get the same 500 error.
I also used Akeeba tools to set fix permissions that did not help either.
I looked at the logs but could not find anything there that would help. I also enabled debug but nothing was reported there either.
Any help would be appreciated.

Solr SolrCore Initialization Failures {{Core}}: {{error}}

All,
I am trying to install Solr 7.2.1. While the installation works, i am not able to run solr successfully. Whenever i try to run, i get the following error.
SolrCore Initialization Failures {{core}}: {{error}}
Please check your logs for more information
I am not sure exactly what the error is. i dont see anything in the logs either. all i see are are some info.
Please advice.
cmd solr.cmd start
or cmd solr.cmd stop -p 8983
doesn't have any issues.
i am running solr in 8982 port instead of the usual 8983. not sure if that makes a difference.
As mentioned by others, this problem is related to the javascript interface not related to the solr server. The same thing happened to me in Chrome. Clearing the site data worked for me.
Clear site data by opening developer tools and going to Application -> clear storage
Important Note:
The usage was 0B before and after clearing the site data but after clearing the site data solr home page came up without any error.
CTRL + F5 did the trick for me :-)
The issue is with the IE only, I have faced the same error. There was nothing in the logs as well. I finally Enabled the JavaScript for IE, Closed all the browser instance and tried again. And it is working perfectly fine for me.
Please refer below image for the reference.

Importing apache logs into piwik

I am in the process of switching my site analytics from GA to Piwik and would like to incorporate all the historic data that I can. I have already concatenated the full trail of apache log files I have in my possession. However, what I do next is not at all clear to me and the Piwik documentation does not help. It says something along the lines of
python /path/to/piwik/misc/log-analytics/import_logs.py --url=http://analytics.example.com access.log
I have my concatenated log file, all.logs, in the log-analytics folder. I would have thought that I just need to issue
python /path/to/piwik/misc/log-analytics/import_logs.py all.logs
but that throws up an error message. When I provide the URL to the site in question too I get an error saying that it gets back an HTML document (naturally) which it does not like.
I'd be most grateful to anyone who might be able to put me on the right track here.
I think --url=http://analytics.example.com let's you set the URL of Piwik, not your website.

New to CakePHP: Need help setting up error log

I'm new to CakePHP. I'm getting an internal server error in my app, but I haven't been able to locate my error log. I looked at the official docs, but I didn't find anything on what the log file is named or where I could find it. I'm not even sure whether error logging is enabled by default. Any help you can offer is appreciated. Thanks.
Look in your /app/tmp/logs/ folder, the file name should be error.log
I believe it is enabled by default, at least when debug is set to 2 in /app/Config/core.php.
Configure::write('debug', 2);

Google app engine down: Server Error

I built a system running on: http://www.hijgoo.com.tw and all the sudden, there was the following message and it did persist. I am using GAE SDK 1.7.2 with Python 2.7. Can anyone help?
Error: Server Error
The server encountered an error and could not complete your request.
If the problem persists, please report your problem and mention this error message and the query that caused it.
Looks like you have a session that does not contain the key account, but your code assumes that it does.
The reason for this isn't easy to see without the actual code, but it sounds like a programming error.
