Something went wrong when I was using the Component Manager to install a module, and now I cannot see my front or back ends.

When I try to do anything through the CLI I get this message:

PHP Fatal error:  Uncaught Error: Class 'Zend_Cache' not found in /chroot/home/urbanta1/devm2.urbantactical.com/html/vendor/magento/framework/App/Cache/Frontend/Factory.php:148

Can anyone tell me what to do? I have looked in the Factory.php, Pool.php etc and I can't tell what is wrong.


  • Do you have any custom cache implemented? That might need clearing Commented Jun 2, 2019 at 22:44

Check the code of the module you are trying to install.

I had the same error and it was because i had Magento core files inside one of the vendor modules. So this files were in conflict with the current installation.
