After installing an addon

Permalink
Installation worked fine. After installing some free addons from marketplace get

An unexpected error occurred.
Cannot use Concrete\Core\Foundation\Object as Object because 'Object' is a special class name.

I am using the newest version of concrete5 and php7.2. (Ubuntu 18.04).
Sorry but i tried everything descript here but i cant get it work.

That's a common problem with PHP 7.2 because Object is already used as a special class name and shouldn't be used as a class name in the package. It's easy enough to fix. If you could let us know which package it is you'd get a fix quickly.

In addition, if you have any problems with Add-Ons, use the support section of the Add-On in question. That way the developer is aware of the problem and can get a fix out to you (and everyone else). It's easy to fix indeed as @mnakalay says, so shouldn't be a biggy.
