One of your extensions/modifications is causing this

first check your OCMoDs - via ftp, delete the contents of your system/storage/modification directory (not the actual directory itself)

Try to login to admin - If you get in, visit your Extensions - Modifications section - Disable all modifications and click the refresh modifications button
Then try enabling one by one the modifications you disabled and click the refresh button after each one.
Logout of admin and back in until you get the blank screen again
The last modification you enabled will be the culprit - Contact the developer of that extension.

If you cannot login after the initial delete of everything in the modification directory, then it will most likely be a vqmod extension that is the problem.
In which case, via FTP, disable all your vqmod/xml files by renaming the file extension from .xml to .xml_ (leave the vqmod_opencart.xml alone though as it is required for vqmod to work)

Also, as above, clear your system/storage/modification directory

Login to admin - Visit Extensions - Modifications and hit the refresh button

Enable one by one the vqmod xml files you disabled

After renaming each one back to .xml - login to admin and refresh your modifications - logout and back in - repeat the process until you cant login anymore.

The last vqmod you enabled will be the problem. Contact the developer of that extension.
