Broken pdf download

dvdmcllstr

Hello,
I unsuccessfully tried to add a custom PDF resolver (based on a url from the institution I work in) in "edit>preferences>advanced" and have now broken automatic pdf download (via the chrome extension) and broken "Find available PDF". Does anyone know how I can reset the preferences to the original? I don't mind re-installing zotero if need be, but would prefer to avoid that.
Many thanks.

Right-click → Reset

Thanks for the quick response. Where do I right-click?

dstillman

On the setting that you changed

When I right click on the resolver I just get options to cut, paste etc. I tried clicking at various locations on the "advanced" section within the "general" tab but cant see an option to reset anywhere.

This is what you changed, not the OpenURL resolver:

Thanks. You are quite right. I did change that. I went back into this however and on right clicking "reset" is greyed out (even when running zotero as an administrator).
If I then modify the value, reset is no longer greyed out. When I hit reset the value is "[]".
That has solved my problem for personal libraries, but for group libraries it is still a problem. I recently purged my storage (https://www.zotero.org/settings/storage?ref=sib). I have however just renewed my subscription for additional storage, so maybe that will solve it.

In case anyone comes across this thread. The problem was with zotfile. A known issue - https://forums.zotero.org/discussion/75347/group-library-and-pdf-access. I had not noticed this before as my group library had been dormant. Thanks for your help @dstilmman
