zim-zotero-plugin not working under Linux Mint

[arn13]

Hi, I have Zotero 5.0.55 installed with the zotxt 5.0.2 addon.
When I try to insert a citation on something that is definitely in my library nothing happens.
I was able insert a citation shortly after installing the plugin a month ago, my guess would be incompatibility caused by an update or something. Any ideas for troubleshooting?
Greetings

Thanks @Drarn for reporting the issue. Can you provide a few details about your setup? E.g.:

• Your Zotero version
• Your Zim version
• Your zotxt plugin version
• Your Python and Linux Mint version
• Any clues as to which update caused the problem

My versions are as follows:
Zotero 5.0.55
zotxt 5.0.2
Python 2.7.15rc1
Zim 0.68-rc1
Linux Mint 19 Cinnamon
Kernel 4.15.0-34-generic

If I remember correctly I switched to that kernel recently, also there must have been some softwareupdates, but not to Zim or Zotero.
The other thing I did was changing from zotero servers to a webdav.
