500 error due to the plugin

Hi, I’m sorry our plugin caused this issue. Looks like the URL structure might be messed up.

Our plugin in the latest version is registering a rewrite rule for the image preview. This may get redirected from www to non-ww or from http to https or vice versa when the addresses are not unified. Can you confirm that this may be the case on your website?

Use ‘LogLevel debug’ to get a backtrace.

Also could you get this backtrace from your server administrator? This will be super helpful for us.

“when the addresses are not unified”. What do you mean with that? We see no errors or non-https etc.

I did check for https, www or not, etc. There is nothing like that.

This is the httaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* – [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Thanks, but that is just the Apache config, not the log ?? This is how it should be enabled: https://stackoverflow.com/a/5767846/12858760 and then this file will contain the log.
