404 and 504

Can you try to re-install the plugin? If there’s a missing file, re-installing it should resolve the issue.

That was sketchy since the ?page=rlrsssl_really_simple_ssl page is not working. Luckily I had a backup to restore to get the mixed content filter working again.

Reinstalling did not fix the issue. This is the third website I have updated that developed this issue.

Strange, I can’t reproduce this behaviour. Do you maybe have a debug log so we can check if there are any errors that could explain this? Since the 5.0.10 update over 1 million websites have updated, I haven’t had any other reports of such an issue.

To generate a debug.log, please add

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', true );
define( 'WP_DEBUG_LOG', true );

to your wp-config.php. Then you can look up the debug.log in the wp-content folder.

Which version did you roll back to?

I did not roll it back. It seemed to be functioning after reinstall, just cant get to settings page.

My reply via email didn’t post. There are no errors in any logs, the datacenters didn’t find any either. WP debug log was not created when the issue happens, so nothing there.

Could you check the server logs to see if they provide any additional information on the 404/504 errors? If the issue is related to PHP it should show up in the debug.log file. What hosting provider are you using?

As I said, there are no errors and the wp debug log file was not created since it wasn’t throwing errors. I don’t have time this week to track this down, but next week I will be doing more investigating.

Hi @adam320,

Do you have any further updates/information regarding this issue?

Just let us know.
Kind regards,
Jarno

I am still having this issue. I do maintenance for clients and after update to wp 5.8 none of these sites will load the settings page: /wp-admin/options-general.php?page=rlrsssl_really_simple_ssl

Can you contact us directly on support(at)really-simple-ssl.com so we can speed up the exchange? It’s very weird. I haven’t had any other reports of this yet. Possibly it’s connected to the hosting environment, can’t be sure.

Hi @adam320,

Based on this thread:
https://www.ads-software.com/support/topic/critical-error-cant-access-options/

We found an issue which can occur if the fsockopen() function is not enabled on the server. Possibly your server has the same configuration.

I have created a version where the plugin checks if this function exists:

Another solution is to ask your hosting company to enable the fsockopen function.

Let me know if that helps!
