!Friendica Support Whenever I try to use the search field to access a post I happened to have seen on a different instance, like friends.brockha.us/display/61b… I get this message "Not Acceptable!
An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security."

Is this a known issue in Friendica v 2022-03 or is it more likely a configuration issue?

It's become particularly frustrating since so many of my friends' instances have updated to Mastodon 4 in which they removed the cool option of clicking REPLY, RETOOT, FAVOURITE, etc. and it brings up a pop-up and asks you to enter your webfinger address bringing you right to where you need to be on your instance, instead replacing that awesome feature, with a wonky instruction pop-up telling you to copy/paste the particularly address on your instance (which doesn't even work at all on Soapbox/GNU Social)


Show instance better when selecting?


!Friendica Support Okay, I have to confess I may have too many single user instances.. but.. :-D
Do I miss a setting? These accounts are on different instances all.

This sounds like an issue with a #waf (web application firewall), not directly #friendica . You should check the logs which rule is triggered and check if it can be disabled.

@Why Reading about ModSecurity™ (which is a journey in itself to find any official information), it looks like these search URLs are being blocked by a specific security rule. By default this incident should be logged in your web server log including the rule that was triggered.

As an absolute last resort because of the unknown side effects, if you don't have access to the web server log or can't disable only the relevant rule, you can disable the whole module for your Friendica node by adding the following lines to your .htaccess:

<IfModule mod_security.c>
  SecFilterEngine Off
  SecFilterScanPOST Off
</IfModule>
