My Mautic version is: v2.15.3 My PHP version is: 7.0 My problem is: since upgrading to this version, campaigns have ceased working, menu items in the Mautic app are not responding (e.g. if I click on channels, emails…it stays on the dashboard screen), and my logs have become full of the below:- These errors are showing in the log: [2020-02-05 00:04:34] mautic.WARNING: PHP Warning - require(/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php): failed to open stream: No such file or directory - in file /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209 {“className”:“Mautic\LeadBundle\Entity\Lead”,“classMetadata”:"[object] (Doctrine\ORM\Mapping\ClassMetadata: Doctrine\ORM\Mapping\ClassMetadataInfo@0000000043b5da290000000016b0d722)",“proxyClassName”:“Proxies\ **CG** \Mautic\LeadBundle\Entity\Lead”,“fileName”:"/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php"} [2020-02-05 00:04:34] mautic.ERROR: PHP Notice: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’) - in file /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209 [2020-02-05 00:04:34] mautic.ERROR: Symfony\Component\Debug\Exception\FatalErrorException: Notice: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’) - in file /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209 [2020-02-05 00:04:34] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalErrorException: “Compile Error: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’)” at /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php line 209 {“exception”:"[object] (Symfony\Component\Debug\Exception\FatalErrorException(code: 0): Compile Error: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’) at /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php:209)"} [2020-02-05 00:04:34] mautic.WARNING: PHP Warning - require(/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php): failed to open stream: No such file or directory - in file /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209 {“className”:“Mautic\LeadBundle\Entity\Lead”,“classMetadata”:"[object] (Doctrine\ORM\Mapping\ClassMetadata: Doctrine\ORM\Mapping\ClassMetadataInfo@0000000049a578b0000000006123ecc9)",“proxyClassName”:“Proxies\ **CG** \Mautic\LeadBundle\Entity\Lead”,“fileName”:"/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php"} [2020-02-05 00:04:34] mautic.ERROR: PHP Notice: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’) - in file /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209 [2020-02-05 00:04:34] mautic.ERROR: Symfony\Component\Debug\Exception\FatalErrorException: Notice: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’) - in file /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php - at line 209 [2020-02-05 00:04:34] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalErrorException: “Compile Error: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’)” at /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php line 209 {“exception”:"[object] (Symfony\Component\Debug\Exception\FatalErrorException(code: 0): Compile Error: require(): Failed opening required ‘/home/mautic/public\_html/app/cache/prod/doctrine/orm/Proxies/\_\_CG\_\_MauticLeadBundleEntityLead.php’ (include\_path=’.:/usr/share/php’) at /home/mautic/public\_html/vendor/doctrine/common/lib/Doctrine/Common/Proxy/AbstractProxyFactory.php:209)"} Steps I have tried to fix the problem: Wet my pants and ask you fine people. ---

Looks like broken cache. Look into this: [Mautic 2.15.3 Installation not working on VPS (PHP 5.6)](https://forum.mautic.org/t/mautic-2-15-3-installation-not-working-on-vps-php-5-6/12394/4) ---
