olafk on "[Plugin: Ultimate Member] Internal Server Error - Custom UM Forms"

Hello,

we encounter an internal server error 500, whenever we try to use a custom um-form in a wp-page or profile tab. Then we get an error like this in the error_log:

[Wed Jun 15 17:22:55.611833 2016] [fcgid:warn] [pid 34589] (104)Connection reset by peer: [client 46.142.11.11:49679] mod_fcgid: error reading data from FastCGI server, referer: https://www.xxxyyy.com/user/sundk/

[Wed Jun 15 17:22:55.611903 2016] [core:error] [pid 34589] [client 46.142.11.11:49679] End of script output before headers: index.php, referer: https://www.xxxyyy.com/user/sundk/

Default forms work fine, but we need to make some changes. I already deactivated

all

Does anyone have an idea how this can be fixed?

Thanks and kind regards,
OlafK
