Amin panel won’t load – critical error on site

@mowse the other reported issues have been resolved, I’ve had no further reports of issues.

Can you enable debugging (for example with the wp debugging plugin), then post the php error you see here?

If you have the pro add on, please ensure that you have the 7.0.7 version.

Thank you for your quick reply, Rogier. We don’t use the Pro version.

Here’s the error:

Fatal error: Uncaught Error: Call to undefined function get_field() in /var/www/vhosts/oscilloscope.net/httpdocs/oscillo-WP-main1/wp-content/themes/oscope2/template-home.php:20 Stack trace: #0 /var/www/vhosts/oscilloscope.net/httpdocs/oscillo-WP-main1/wp-includes/template-loader.php(106): include() #1 /var/www/vhosts/oscilloscope.net/httpdocs/oscillo-WP-main1/wp-blog-header.php(19): require_once('...') #2 /var/www/vhosts/oscilloscope.net/httpdocs/index.php(17): require('...') #3 {main} thrown in /var/www/vhosts/oscilloscope.net/httpdocs/oscillo-WP-main1/wp-content/themes/oscope2/template-home.php on line 20

…but that error persists whether the Really Simple SSL plugin is activated or not. What’s odd is that when it’s activated, the homepage displays a critical error page:

When it’s turned off, here’s what appears on the homepage:

…and here’s what I see for the admin panel:

I’d so appreciate any thoughts you’d have.

Thank you…

@mowse the php error is not caused by Really Simple SSL, it is coming from your theme. If you enable debugging, it shows up on your home, so that explains the behaviour with debugging enabled. It could also cause the white screen from Really Simple SSL, because it possibly returns the error in the response to the rest api.

Can you check if the you still have the admin panel issue with a default WordPress theme?

I resolved the error I posted above, which I determined was related to Advanced Custom Fields.

Even with a default theme activated (and all other plugins off), the admin panel loads as it does in the screenshot above.

I thought it was strange that even the RSSSL logo wasn’t loading, and I discovered an .htaccess file in the wp-content folder with this code:

# PROTECT wp-content
Order deny,allow
    Deny from all
    <Files ~ ".(xml|css|jpe?g|png|gif|js)$">
    Allow from all
    </Files>

When I renamed it (so it isn’t active), the RSSSL logo loaded — but none of the other panes are loading, and the Settings tab link doesn’t do anything.

Does that offer any clues?

More info that I’m trying to make sense of:

This site was migrated from Media Temple to GoDaddy. I wasn’t the one who installed RSSSL on this site. The WordPress admin area is running on https. (I see the valid certificate when I click the padlock.) But the front end of the site is running on http. And the Site Address (URL) in General settings is still set to http. Could that be part of the problem? Should I change it to https?

UPDATE: In Chrome, the front end of the site is https (and says it’s protected), but in Safari it’s not.

FYI: I left the admin panel page up for a while in Chrome, and this finally loaded, but when I refreshed, it doesn’t load again.

This also appears sometimes after it sits for a while:

This loaded in Chrome after sitting for quite a while:

Hi @mowse,

I visited the attached URL and it appears that your site is currently experiencing a 500 Internal Server Error, which I would expect to be the reason for the described behavior that occurs when visiting the Really Simple SSL Dashboard.

Unfortunately, these errors are not very descriptive on their own. I would recommend checking the server error logs, as these should provide more detailed information regarding the cause of the error (and what actions the server is trying to perform when the issue occurs).

Kind regards, Jarno

Hello
I’m using wordpress 6.3.1
I updated the “really simple ssl” plugin this morning, and since then, when I browse the site, the administration bar is no longer displayed on the home page, but only on the article pages? ?
I reinstalled the previous version (7.0.7) of the plugin but the problem persists.
A solution please?

Thank you, @jarnovos for pointing that out … I will look into it right away.

@rogierlankhorst … Am I correct in thinking that Site Address (URL) in General Settings should be set to https?

@mowse yes, the site url should be https. If SSL is activated in the plugin, it will set this to https automatically. If this is not the case, it is probably in a deactivated state.

Easiest way forward is to change the home and site url to https.

Thank you so much. I got the 500 error resolved with the host, and now the admin screen is loading as expected. Thanks for your help!
