Error while deleting submission

Hello,

as some other people around here I am facing a problem while deleting a submission.
Sadly no solution i tried within this forum was able to fix the issue. I would appreciate any help.

If i try to delete a submission following error occurs:

##api.submissions.unknownError##

The console shows:

Failed to load resource: the server responded with a status of 404 ()
ModalHandler.js:214 Uncaught TypeError: Cannot read property 'trigger' of undefined
at proxyConstructor.$.pkp.controllers.modal.ModalHandler.modalOpen (ModalHandler.js:214)

at ModalHandler.js:204
ModalHandler.js:210 Uncaught TypeError: Cannot read property 'focus' of undefined
at ModalHandler.js:210

The PHP log is not very revealing as well:

Config:

disable_path_info = On
restful_urls = Off
client_charset = utf-8
connection_charset = utf8
database_charset = utf8
charset_normalization = Off

Everything else works as expected.

OJS Version: OJS 3.1.1-4

Thanks in advance!

I have the same problem on OJS 3.1.1.4.

This is my shown in my console:

Any Idea?

My problem was caused by .htaccess file.
After moving .htaccess from root folder, everything worked fine. I have to check which of the commands in htaccess caused the error.
