After updating Helix Ultimate (to resolve yet another security BUG in JoomShaper code), I now can't access ANY page on my site which contains a link to EasyStore. Instead, I get the error code:
Class "Joomla\CMS\Filesystem\Path" not found
I have re-installed EasyStore
I have deleted SPPageBuilder cache
I have deleted template CSS, JS & SCSS cache
I have deleted Joomla cache
I have deleted browser cache
I have disabled SEF
...NONE of those actions have worked, so I'm now left with a site which does not function
