CacheCleaner: ClassNotFoundError after install...

I am working on a new J4 website and installed CacheCleaner 8.0.1 today.

I backed up the site using Akeeba Backup and attempted to install it on another development site.

The front end was blank.

When I attempted to log in, I got the following message:

Error > ClassNotFoundError HTTP 500
Attempted to load class "ClacheCleaner" from namespace "RegularLabs\Module\CacheCleaner\Administrator\Helper".
Did you forget a "use" statement for another namespace?
Exceptions 2 | Stack Traces 2
Symfony\Component\ErrorHandler\Error\
ClassNotFoundErro
in /home/mydomain/my.subdomain/administrator/modules/mod_cachecleaner/mod_cachecleaner.php (line 62)

Plus a load of other references see image:


When I disabled the plugin, backed up and installed on the new domain, all is fine.

That worked. Thank you.
