Menu links point to blank pages after template update

headcake

I've tried updating my Shape5 template "Arthur" to the J4 update on my J3 site in preparation for upgrading to J4. The site crashed and I restored it. Formatting had changed in a few areas of the template that I have been fixing one at a time. Now the main menu links all go to blank pages. The URL shows correctly, but the pages are blank.

I turned on error reporting and it shows:

Notice: Trying to access array offset on value of type null in .../templates/arthur/vertex/parameters.php on line 77

Notice: Trying to access array offset on value of type null in .../templates/arthur/vertex/parameters.php on line 93

Both of those lines show:
$admin_options[(string)$item['name'][0]] = (string)$item['default'][0];

Are you using latest version 1.0.7 of this template? https://www.joomlart.com/member/downloads/shape5/joomla-templates/s5-arthur

If yes, you can share the super admin + FTP account so we can check directly for you.

Yes, version 1.0.7 is the version I installed. Since the site crashed when I installed it, I had to restore from a backup. After the restore, the links don't work and I get the template error. I can't install the current version of the template because the site will fail so right now the site is using the J3 template. Not sure what to do but I did create a super admin account for you.

headcake Hi

I think the problem comes from your backup, something wrong with it as if you switch to Protostar template, you can't access links either, it's not issue of Arthur template. Do you have any other backup?

headcake

saguaros Unfortunately I have two backups, both show the same errors. I've tried the htaccess file, and checked the configuration.php file, but the only errors I get when turning on error reporting is template errors on those two lines. If it's not the template, I'm not sure where to look.

You can contact your hosting provider for help to investigate further, the 500 error is server error:

Maybe there is rule in server side affect this.

As I'm digging further into this: with Error reporting set to maximum, when I click on a menu link I get the following:

It looks like you're using old version of S5 Disqus comments plugin, you can backup your site and install latest version first: https://www.joomlart.com/member/downloads/shape5/free-joomla-extensions/s5-disqus-comments-plugin
