Hi @vdghf_vcxzv
I understand the problem you are facing !
But as you mention that you have changed in your custom theme - so off course its requires to run the deploy command !
Because assets , Images , JS all are served from pub directory - so you need to run the below command :
php bin/magento setup:static-content:deploy -f
But still as an trying purpose - i would say change it to production mode , so it will automatically do static-content:deploy - but this is just suggestion not sure it will work or not !
try this , but its always good if we have command line access to run commands !
hope it helps
