I deleted a module without disabling and uninstalling it first. Now I just get a blank white screen, but I don't see any error messages. What can I try to fix this?
Run the following query.
select info from system where name = 'module_name';
You will get a blob. Within this blob look out for text after
version. You can find the version of the module here.
Download this version of the module. Place it in
sites/all/modules folder(you can also find out the previous location from the file-name field in system table), uninstall the module. Now delete the module.
If you put it back and then disable it and uninstall it again.
You need to supply some additional information:
- The version of Drupal (5,6,7,8?)
- The name and version of the module
I've previously restored the database of Drupal 6 to a site without all the modules and never got a blank page so it must of been a pretty important part of the site.
Are you sure you can't access the ?q=/admin page? Even if you can't access the rest of the site these pages maybe unaffected.
