“ERR_EMPTY_RESPONSE” when click “See Library”

This works perfect:

How was this resolved?

Hi @etwei2wp,

As per forum guide, please start your own thread. You are welcome to cross-link it to this thread, so we are aware of both.

Meanwhile, please try adding the following snippet to your .htaccess file and see if it helps.

<IfModule mod_substitute.c>
SubstituteMaxLineLength 10M
</IfModule>

Kind regards,
Herman ??

Hi Herman,

Adding the snippet to .htaccess helped, no more getting “This page isn’t working didn’t send any data. ERR_EMPTY_RESPONSE”. Thanks.
