I was trying to create a synonym on Arts & Crafts. Clicking the 'Create Synonym' button threw this error:
It seems the 'Create tag synonym' pop-up got replaced by the code of the (error) page I would normally (?) be redirected to:
<!DOCTYPE html> <html class="html__responsive " lang="en"> <title>Oops! Something Bad Happened - Arts & Crafts Stack Exchange</title> [&c...]
It doesn't seem to matter on which tab of the synonyms page I click on the 'Create synonym' button.
Note that the tag I wanted to create a synonym for did not yet exist (I anticipate its use).
The way the error was thrown was not caused by Dark Reader (visible in the screenshot — I mention it because it's the only plugin I have that changes the visual layout of pages in Firefox).
- Firefox v. 101.0.1
- Windows 10 Pro 19044.1706
