Hi guys, the issue was fixed by setting this for the vps. php app/console cache:warmup --env=prod ---

Seems like crons are not working and giving following error, after running above command. ``` require(/var/www/html/app/cache/prod/doctrine/orm/Proxies/ __CG__ MauticLeadBundleEntityLead.php): failed to open +stream: No such file or directory in /var/www/html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php on line 209 PHP Fatal error: require(): Failed opening required '/var/www/html/app/cache/prod/doctrine/orm/Proxies/ __CG__ MauticLeadBundleEntityLead.php' +(include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php on line 209 ``` ---

It very much looks like PHP timed our before finishing creating your cache. Can you increase PHP timeout limit? I experienced systems where it took 2.5 min to warmup the cache. ---

Also I recommend upgrading PHP to Version 7.2, at least some 7.x (but not yet 7.3) 🤓 ---

Thanks dirk, If i increase the PHP timeout limit, will it also fix the screenshot error as well? i tried this on same VPS with php 7.0 and it was giving same error. ---

Mautic files/directory (app/cache) must be writable by the web server user. ---

apache owns all the files and directory of mautic and i have also set the 755 on folders and 644 on files, but still getting the error. I am curious why everything runs perfectly fine when i install 2.15.0. Any thoughts on that as well. ---

Did you run that PHP command (php app/console cache:warmup ) as root user? If you did, the web server user can’t write there as only root has permission to do so. `find -user /var/www/html/app/cache` ---

Yes, i ran above command as root user, i have switched user to apache using following command `su -s /bin/bash apache` Then warmup the cache and crons are running perfectly fine. Thanks for your help @MxyzptlkFishStix.
