**Your software**  
My Mautic version is:2.16.3  
My PHP version is:7.2

**Your problem**  
My problem is:  
Just upgraded using CLI from 2.16.0 to 2.16.3 and Mautic stopped working - I am getting this in the log file

These errors are showing in the log:  
mautic.ERROR: PHP Notice: require(): Failed opening required ‘\<my\_path\_here\>/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_Mau  
ticPluginBundleEntityPlugin.php’ (include\_path=’.:/usr/local/php/7.3/7.3.22-dh34/lib/php’) - in file \<my\_path\_here\>/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209

Any hints?

Yes, tried with 7.3 but the same error getting with 7.2. 7.3 is supported by 2.16.x right?

not sure if this was that, but now Mautic 2.16.3 is working.
