Hi, It’s the first time for me using mautic. I just installed version v2.12.1. Now I’ve a problem using mautic, because the email builder and the landingpage builder doesn’t load. On the left side I see just a blank site, on the right side there is the tool bar. I recorded a short clip to show you the problem: [https://www.youtube.com/watch?v=iebIOxOq8bE](https://www.youtube.com/watch?v=iebIOxOq8bE) What can I do? ---

I have the exact same problem since some time. If clone an old email, the builder will work, if I crate a new one, the builder shows an empty page as above. Everything was working fine before the update to 2.12. Here is part of the log, which seems to contain a critical error: `[2018-01-16 16:55:48] mautic.CRITICAL: Uncaught PHP Exception RuntimeException: "Unable to create the cache directory (/var/www/mautic/app/cache/prod/twig/de)." at /var/www/mautic/vendor/twig/twig/lib/Twig/Cache/Filesystem.php line 57 {"exception":"[object] (RuntimeException(code: 0): Unable to create the cache directory (/var/www/mautic/app/cache/prod/twig/de). at /var/www/mautic/vendor/twig/twig/lib/Twig/Cache/Filesystem.php:57)"} []` Any idea what could fix this? Thanks! ---

Thank you, Bizcrony, this fixed it. I just cleared the cache with `rm -rf app/cache/*` and visited [https://MYHOST/mautic/s/update/schema](https://MYHOST/mautic/s/update/schema), which stated that the schema is already up-to-date. Thanks! ---

I also have a fresh installation in the version 2.13.1. The builder doesn’t load and I got this error: ```auto [2018-06-05 12:59:26] mautic.CRITICAL: Uncaught PHP Exception Mautic\CoreBundle\Exception\BadConfigurationException: " is missing a required config file" at /usr/share/nginx/html/mautic/app/bundles/CoreBundle/Templating/Helper/ThemeHelper.php line 71 {"exception":"[object] (Mautic\\CoreBundle\\Exception\\BadConfigurationException(code: 0): is missing a required config file at /usr/share/nginx/html/mautic/app/bundles/CoreBundle/Templating/Helper/ThemeHelper.php:71)"} [] ``` the missing config file ist existing. Any idea how I have to fix this problem? Thanks! ---

For me the problem was here: [2018-06-20 19:28:12] mautic.CRITICAL: Uncaught PHP Exception RuntimeException: “Unable to create the cache directory (/opt/bitnami/apps/mautic/htdocs/app/cache/prod/twig/68).” at /opt/bitnami/apps/mautic/htdocs/vendor/twig/twig/lib/Twig/Cache/Filesystem.php line 57 {“exception”:"[object] (RuntimeException(code: 0): Unable to create the cache directory (/opt/bitnami/apps/mautic/htdocs/app/cache/prod/twig/68). at /opt/bitnami/apps/mautic/htdocs/vendor/twig/twig/lib/Twig/Cache/Filesystem.php:57)"} [] Fixed privileges for /opt/bitnami/apps/mautic/htdocs/app/cache and problem solved!
