The error message as running the search

[qinggrain]

Why I run a search in Webscrapbook and got the following message.

Scrapbook “scrapbook” seems to have an outdated fulltext cache. Click me to update it and then refresh this page.
Error: The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

What is the version of your OS, browser, WSB and PyWSB?

Do you see any error in the server log?

Please update your WSB extension and PyWSB to the latest version and try again.

If the issue still persists, please provide the <scrapbook directory>/tree/fulltext.js file (or similar file if you have tweaked the paths in the config), or at least the item which looks like:

 "20250930*********": {
  "index.html": {
   "content": "..."
  }
 },
