Hi,

Thank you very much for all the details!

The issue is, that the ajax request returns an incorrect response, it basically returns the whole site as the request response. These issues usually happen when:
– There is either a function declared somewhere, that interrupts the execution, mostly code that checks for $_POST or $_REQUEST variables
– More likely, there is a malformed mod_rewrite rule within the root .htaccess file
I would first recommend checking these, it is very likely one of them causing the problem.

As a bypass, you can try enabling the custom ajax handler feature, which may circumvent this problem, however I still recommend investigating what exactly is interrupting the ajax handlers.

Best,
Ernest M.

Hi Ernest,
thanks for the feedback – I forward to our devs – mod_rewrite / .htaccess is a good tip.

Let you know how we go.

Thanks

Hi Ernest,

after a long testing session we were able to pin down the issue to a plugin which requests member information through an API token. Activating/deactivating that plugin enables/re-enables the issue. So… this is not a bug in relation to your plugin but your search plugin is affected by the behaviour and restrictions of the other one.

I leave this thread open it might be useful for someone else in future and if we find a feasible solution to avoid this clash I will post it here.

cheers

Thank you very much for letting me know!
