Hello,

We renewed our subscription to Route 66 and downloaded the updated file. When we reinstalled it, it has created an hour that is being thrown across the entire website. Fortunately, this is a development site, but it has halted all volunteer work over the weekend, which is super valuable because we are an all volunteer force.

The error it is throwing is:

An error has occurred.
0 Failed opening required '/home/bdsmclas/public_html/dev.seleatherfest.com/plugins/system/route66/lib/plugin.php' (include_path='.:/opt/alt/php82/usr/share/pear:/opt/alt/php82/usr/share/php:/usr/share/pear:/usr/share/php')

 

Please help and advise what can be done. We literally can't get any Paige on the backend or front end to render every single page is throwing this error.

 

Thank you in advance for your quick attention.

Hi Catherine,

This error indicates that there are some leftover files from the previous Route 66 v1.x series. The installer attempts to remove these automatically during the upgrade, but in some cases Joomla prevents the cleanup from completing.

If you have access to the filesystem, please try renaming the following folder:

plugins/route66/k2

to:

plugins/route66/_k2

This will prevent the old plugin from loading and should resolve the issue.

If the issue persists, try the same with:

plugins/system/route66pagespeed

If you prefer not to make the change yourself, please create a private support ticket and provide FTP or hosting file manager access (or database access if that’s easier). I’ll be happy to fix it for you as soon as possible.

Sorry for the inconvenience.

Thank you for your swift reply. I made changes to both files as suggested and the same error is repeating and the circumstance has not changed. Further suggestions pls?

Thank you.

Hi Catherine,

Since you have access to the filesystem, rather than guessing which leftover plugin is causing the problem, let’s enable Joomla’s debug mode so the error message will show us the exact file that is still being loaded.

Please edit your site’s configuration.php file and make the following changes:

public $debug = true;

Save the file and reload the page that shows the error.

The error message should now include a full stack trace or at least reveal the exact file that is trying to load the missing library. Please copy the complete error message (or send me a screenshot), and I’ll tell you exactly which leftover file or folder needs to be removed or renamed.

Once we’ve resolved the issue, you can revert the settings back to:

public $debug = false;

Alternatively, if you prefer not to troubleshoot this yourself, you can create a private support ticket and provide temporary FTP access. I’ll be happy to investigate and fix the issue for you.
