Dear Route 66,
Upon updating to the newest version of Route 66, we ran into the issue where the following error message has popped up.
Failed opening required '/var/www/vhosts/btn.nl/httpdocs/plugins/system/route66/lib/plugin.php' (include_path='.:/opt/plesk/php/8.3/share/pear')
And when we look at the server's PHP version we see that it is set to PHP 8.3 so could you help us resolve this issue?
Kind regards,
Raoul Alderse Baas
Hi Raoul,
Thank you for reaching out.
The error you’re seeing suggests that the installation didn’t complete properly, since the file in question is no longer part of the new version of Route 66. Could you confirm whether Joomla reported the installation as successful?
Please make sure you’re updating to the latest release (version 2.0.5). Your PHP version (8.3) is fully compatible — Route 66 requires PHP 8.2 or later.
If your site is not accessible due to the error, you can temporarily disable Route 66 by renaming the fileplugins/system/route66/route66.php
to something else. This will let you regain access to your site.
After that, I recommend reinstalling version 2.0.5 to ensure all files are correctly updated.
Kind regards,
Lefteris
