How to fix error "maxClauseCount is set to 65536"? Appearing during startup and importing feed

[carloscadux]

Hi. I'd appreciate your help.

The following error appears in two situations:
a) Every time RSSOwlnix starts
b) Every time a new feed is imported (although the error appears, the feed importing is concluded).

An internal error occurred during: "".
maxClauseCount is set to 65536

When I started using RSSOwlnix there was no error at all.
The error appeared recently.
After I close the error pop-up window RSSOwlnix keeps working normally.

=> How to fix this error?

Thank you,
Carlos

try a clean up. you dont need to remove anything (deactivate checkboxes that remove stuff on 2nd step) but at least do the 2 improvements to performance (on 3rd step). Tools / Clean Up...

Thanks for your prompt reply Xyrio 👍
I performed the Tools / Clean Up procedure as instructed by you, but the error is still there.
I recorded my screen detailing the issue and the performed procedure: https://bit.ly/3I0lkOU
Would you suggest anything else I could try to fix the issue?

that error is somehow related to searches (maybe filters too?).

i think the reason might be because of some saved search that has too simple conditions which returns too many results.
there are at least the saved searches created by default. either delete them or add a condition so they match less (like only within 360day): "Labeled News", "News with Attachments", "Sticky News", "Todays News", "Unread News"...

there might be a search (or filter?) that has an empty condition? like only a space or a word that is ignored by the search engine like "the" and other so called stop words https://www.computerhope.com/jargon/s/stopword.htm

you can make a backup of all the content in %userprofile%\.rssowlnix-beta\.metadata\.plugins\org.rssowl.core. then you can restore it manually after trying stuff out.
after backup, try things until error disappears:

• delete saved searches
• deactivate all filters?
• delete all filters?
• delete older news either manually deleting news feeds gradually completely (try causing error after a few) or by using cleanup to gradually delete news older 360,180,30,1 days
