Hello. I encountered a 403 error while while putting a script from another platform (artwork archive) which I wanted to embed on my WordPress page using Beaver Builder text editor. I checked how to fix and saw an instruction to add a code to allow the new script that is being blocked to be saved. Where do I place the code:
define( ‘FL_BUILDER_MODSEC_FIX’, true );
on my wp-config.php? I am not a web developer and I am afraid to mess up the codes in there i.e. authentication keys and salts, debugging, etc. Can someone please help point out where exactly should I add the said code in wp-config.php?
Thank you
you put the line anywhere above this line:
/* That's all, stop editing! Happy blogging. */
Thank you. Issue resolved.
I have this same issue but using the solution above didn’t work :-/
