Filters not working any more

Ahm, I tried different things, and yes, when using checkboxes I saw that the filter has brackets added (for multiple values), but I didn't configure checkboxes and it doesnt work with any setting.

hello

then i would like to look at this you can send me a pm with website access

Thank you, that's very kind of you. I sent you a PM with a Joomla super user access.

Sorry I don't mean to stress but have you had the chance to look at it? Otherwise I might have to restore the website from before the update, as the client is asking.

Dear ggppdk,
May I get another chance to get this looked at? This would be very kind.

I can send you another page where the filter doesn't work, and one, on which it works. They both use the same version of flexicontent and joomla. I have compared the filter settings of that date field with the one that still works, and even if set to exactly the same, it has no effect.
Also checked the database, and as a test I changed the collation of most of flexicontents tables to the new utf8mb4, but it all has no effect and I can't see any difference. I have also looked at the search index and have reindexed it after the changes. Also, I have tested again with different templates, but all of them use the standard filter form.

I have no idea where else to look for it. On one page I have set up a hidden menu I can show you with the filter active, and there is no difference to the generated URL of the filter form in comparison to the one that my calendar module generates )the only difference is that my calendar module is not a form, but I think it should make no difference with GET...

Hello

i see that the credential that you sent me, some time ago , still work

i have logged into the website, i think i can look at this now
