@eduardomozart I’m afraid this repository is no longer active. Is your fork OK? Can I install it instead? Thanks anyway.

[eduardomozart]

@dwp-forge still has active contributions this month on his GitHub page, so I think eventually he'll review my PR. I'm using it without issues so far. After applying the fix, make sure to follow "Note for users upgrading" on the footpage of the PR.

Thank you very much @eduardomozart
I’ve carried out the update and installed your fixes, and everything’s working perfectly! Have a lovely day.

@prolibre,

If any page in your wiki had a small syntax typo (like a missing quote or bracket), the parser would get stuck and eventually crash when trying to parse valid references on subsequent pages.

I just merged a fix that properly resets the parser state for every page at bf309d0 that's now part of PR #83.

Important: After updating, please delete the plugin's cached index at data/cache/refnotes_database.index (or resave an affected page) so the plugin can properly re-parse your citations.
