[OJS] QuickSubmitt plugin installation without tar and exec

Description of issue or problem I’m having:
We are trying to install an add-on on shared hosting where the administrators have disabled tar and exec functions.

Steps I took leading up to the issue:
We have manually uploaded content of plugin folder in /plugins/importexport/quickSubmit folder and tried enable it in plugins but we got infinite loading when trying to open plugins page. If we try to do upgrade on site we get error 500 (cant get php error log, hosting providers do not provide it).

What I tried to resolve the issue:
Trideo do contact server administrators but without success.

Application Version - e.g., OJS

Hi @knjigor

If you have terminal CLI access to the server, have you tried to git clone the plugin to the folder?
