Mornin Y’all..

After updating to WP 4.5 and the latest SP I’m experiencing a fatal error creating a new topic. Ran repair on all sp databases and dumped cloudflare cache.

Fatal error: Call to undefined function mb_convert_encoding() in /home/ebms/public_html/blog/wp-content/sp-resources/forum-plugins/plupload/library/sp-plupload-components.php on line 980

Browser console error. Could not write session state file  TypeError: this.Paths is null
Stack trace: Agent.write@resource:///modules/sessionstore/SessionWorker.js:161:9

Had this error yesterday when editing an existing post and adding a new image.

Thanks for your help.. wink

Yep.. But not sure what post you are referring to.

BTW replying to existing post does the same thing.

fidosysop-2 FYI: Installing mbstring resolved the exact same issue I was having, discussed in that other topic. Here is the resolution explained.

Sorry you had this trouble, but glad to know I wasn’t the only one!

I had no clue – thanks again to Jim for the tip.

Is that module something new to WordPress? I assume it is since the recent problem.

no, not new, wp has used multibyte stuff for long time since some languages require more characters  …  but you probably just never did anything to invoke it..
