I tried clearing the cache from within Docker and its terminal and now I keep getting this fatal error:

“ **Twig\Error\RuntimeError:** An exception has been thrown during the rendering of a template (“PHP Warning - filemtime(): stat failed for /var/www/html/var/cache/de\_/AppKernelDevDebugContainer.php”). - in file /app/bundles/CoreBundle/Resources/views/Default/script.html.twig - at line 7"

I ran this command in the Docker terminal: php console cache:clear

A theme I was working on did not appear when I created a new email, so I attempted to clear the cache.

A bit more of the error:

- **/app/bundles/CoreBundle/Resources/views/Default/script.html.twig:7** at

I noticed that Mautic didn’t recreate the cache directory. I thought it was due the file permissions so I changed file owner from me to www-data:www-data and 775. That only made things worse 🙂

I’ve never used DDEV before. Can I restore the files from the container image?

I’m also curious regarding how to disable caching while creating themes so I don’t need to manually clear the cache on every change.

Thank you.

I see no issue here and `ls -al var/cache` ?

What is the output of `bin/console cache:warmup` ?

Hi,

Now I’m seeing a Bad Gateway error.

Did ddev restart and now it’s working. (fingers crossed!)
