# Fatal Error – Install Procedure – Admin.php

 * I’ve updated my CSS JS plugin to the latest version 11.2, WordPress is version
   5.6 and I’ve moved PHP to 7.4 (but I’ve also tried 5.6, 7.0, 7.1, 7.2 and 7.3).
 * I can’t run the CJT Installation Procedure, I just get a Critical Error wordpress
   page.
 * I get no errors in the logs. PHP memory is 2048MB. I’ve cleared htaccess of anything
   other than the basics.
 * The only thing I notice is in the console, a 500 error on admin.php?page=cjtoolbox
   line 1.
 * Any ideas how to progress, or what to check?
 * Thanks,
    Nick

 * Hello there,
 * I am really sorry for the delay as I have been on vacation. Sorry for the inconvenience
   you are experiencing.
 * I should ask, are you still having issues with the installation procedure?
    Or
   did you manage to resolve it.
 * Thanks

 * I just checked you website and noticed via View Page Source that you are running
   a CJT Code Block successfully.

 * Hello,
 * Thanks for the response. Yes, I got it working. Looks like some problems with
   the theme and latest versions of wordpress/PHP. I ran the install procedure by
   switching temporarily to a different theme. Definitely problems with the theme
   though and not the plugin.
 * I should have updated this post, sorry but thank you for the reply!
