Phoca Gallery Options not working

[zed19]

Under Joomla 4.21 when I try to edit the options I get this:

500 behavior::modal not found.

Any help?

Hi,

we need more information please. PG Version, which Template? Did you migrate from Joomla 3 Version to Joomla 4 etc.

Turn on the "debug mode" setting of the Joomla configuration to see the "Call Stack".

Kind regards
Christine
