HTTP ERROR 500 WordPress Azure App

Question

Greetings for the day.

My Azure WordPress site http://sibeeshpassion.com/ is giving me an HTTP ERROR 500. To resolve I had done the following the fixes already, unfortunately, none worked.

1. Creating new httaccess to check whether it is corrupted Setting limit in Wp-Config
2. Creating new php.ini file in Wp-admin with limit
3. Now I need to disable the plugins and find out which plugin is causing this issue, as the site is down, I can not log in and do that. So the only option is FileZilla or FTP. But when I try changing the folder 'Plugins' I am getting access is denied message.

Any solutions available? Your help is much appreciated. Thanks in advance.

Answer 1

I would suggest you check the FREB log to see what model gives the 500 error.

You may check the below link to enable diagnostic logging for web app

After stopping the App Service in the Azure portal, I was able to rename the folder name. To stop, please do the preceding steps.

• Login to Azure Portal
• Go to the App Service
• Click on Stop as showing in the below image

Once after renaming the plugin folder, my site was up and running. Then I uploaded the plugins one by one and found wp-super-cache plugin was causing the issue, hence deleting that fixed the issue permanently.

Hi, to detect what is causing the generic HTTP 500 error, you need to enable the debug mode on Worpress:

Open the file "wp-config.php" and make sure that define WP_DEBUG is true:

define('WP_DEBUG', true);

After That you will be able to figure out the kind of plugging or files are causing the issue.

If you need to manually disable a plugging or theme, you only need to rename plugging/theme folder to "anyname"-disabled:
