Hi @puregraphx,
I suspect that there is a conflict with one of your other active plugins/custom scripts. Do you have any other plugins/JavaScript active on the site that you suspect might be able to cause this?
Disabling the other plugins one-by-one would likely be the best course of action here.
Kind regards,
Jarno
Hi @jarnovos
When we disable all plugins except Complianz, then we can do 5 consecutive scans without a 502 error, but as soon as we enable any other plugin, the problems occur, doesn’t matter which plugin.
We first tried with the Elementor combo, 502, then with only Duplicate Page or Enable Image Replace which are rather small plugins, again 502.
Hi @puregraphx,
You can add the following lines to your wp-config.php file to generate a debug log & enable script debugging.
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'SCRIPT_DEBUG', true );
We can have a look at the server logs. In any case, our Cookie Scan works by turning the scanned pages into iFrames and checking which Cookies are detected. As a result, this functionality should not really be able to break anything.
Kind regards,
Jarno
I have enabled logging, but there is absolutely no debug.log to be found.
Hello @puregraphx,
The default location of the logfile is usually “/wp-content/debug.log/”. You could also change the WP_DEBUG_LOG line I mentioned earlier to set the desired location to save the file instead, example below:
define( 'WP_DEBUG_LOG', '/tmp/wp-errors.log' );
Let me know if you have any updates.
Kind regards,
Jarno
Yesterday, we disabled Varnish cache on our VPS, after that we were unable to reproduce the error. We have enabled Varnish, but still don’t see the issue. Maybe Varnish was not the cause? Maybe disabling Varnish fixed it/something, can’t be sure.
Hi @puregraphx,
Thank you for the update.
If this happens again and Varnish cache clearing/disabling seems to help, just let us know and we can have a closer look at what the exact cause could be. I’ll mark this thread as resolved for now.
Kind regards,
Jarno
