After upgrading a 4 year old MODX website from version 2.2.x to the latest version I get this error message:
Class 'Masterminds\HTML5' not found in […]/core/cache/includes/elements/modplugin/5.include.cache.php on line 26
How can I fix it or is it better to make an upgrade to v2.3 or 2.4 at first?
BTW: it’s a front end issue. The manager works well.
If you look at /core/cache/includes/elements/modplugin/5.include.cache.php on the files tab, checking around line 26 or for an include or require line above it may tell you where it's looking for that class file.
Though, on second thought, it may be a registered extension package. I think the process or the database format for that changed in one of the major upgrades you skipped, so the proper conversion may not have been done.
Thanks for your replies! I updated to modx 2.3.2 - and had the same issue. In the 5.include.cache.php is in fact a referral to a plugin I installed. Updates weren't supplied anymore but a new version of the plugin. I installed it and everything works fine now
