Stopped working

I am not sure what is your problem , probably you will need to clear your browser cache as well.

Or you can try the ajax template to see if it is working.

I have tried to clear browser cache + reset browser to defaults.
I have noticed in the URLs that when I press on search button, plugin builds URL this way: [metakey]=regij&cmf[0][compare]=1&cmf[0][value]=uwpqsfcmfall – this should work (as it worked before) but it doesn’t.
After clearing cache directly from page (in the wp bar there is performance tab that w3tc outputs and you can click on it and empy cache from there) URL is: [metakey]=regij0cmf[0][compare]=10cmf[0][value]=uwpqsfcmfall

Look the difference:
[metakey]=regij&cmf[0][compare]=1&cmf[0][value]=uwpqsfcmfall
[metakey]=regij0cmf[0][compare]=10cmf[0][value]=uwpqsfcmfall

– cache reset changes URL in a way it replaces “&” with numbers.
Starts with 0 and goes 12345… for every “&” sign in URL.
Strange is that plugin returns results only with those numbers when clearing cache changes URL.

I have tried complete removal of w3tc from various guides found online (uncheck all options -> deactivate -> delete -> remove files from server) and problem persists.

Please tell me what to do to fix this.
I can provide access to wp-admin if needed via personal contact.

Problem solved by restoring whole WordPress website to an earlier version.
Possible reason of this bad behaviour could be that some options in w3tc didnt perform as it should.
I have noticed message (something like): “W3tc now uses standard setup options as config dat couldnt be found” after restoring backup.

I have deactivated and deleted w3tc plugin and for now, there is no bad behaviour.
