Hi Kevin, if you look at the following part of that URL query you can see that it’s basically looking for events with the keyword ‘Search’ somewhere in the title or post content:
tribe-bar-search=Search
And indeed the word searching can be found in amongst the copy for the single event that is listed.
This can happen when a type of script called a polyfill removes our placeholder text reading ‘Search’ and replaces it with a new piece of text, saying the same thing but added as the actual field value. Traditionally this is done for cross-browser compatibility reasons and ideally the script will clean up before any submissions are made.
My guess is that your theme or a plugin you are using adds this polyfill script and for some reason it isn’t cleaning up after itself … whether that’s a bug with that particular script or something else is breaking it / causing an error earlier on I can’t really say.
I can’t be absolutely sure that’s what is happening as I do note that when you opened the thread you marked down having tried deactivating all other plugins and switching to a default, unmodified theme – normally I would expect those steps to resolve an issue like this – so with that in mind can I just double check and confirm that you did in fact run through those steps and ask you what the outcome was?
Ideally we’d be able to narrow the problem down to a script enqueued by another plugin or by your theme and take action from there but, of course, if that isn’t the problem we can investigate other angles.
