can you check the server error log?  basically the server never responded to the request, so it timed out and we could just output a message…

Hi, sorry, I was traveling and needed some time to look into this. I just went through the process myself and get the same error when trying to upload an image for the sig. It will let me add html for the sig so long as the image is already hosted somewhere, it just won’t let me upload an image. Server is not having any issues. Any ideas?

Also, not sure if this helps or not, but I can upload images to a forum post just fine. Just not for my sig.

well your initial message was pre wp 3.9 and sp 5.4.2…  have you upgraded to the latest versions (definitely wont get tinymce not defined message)??

Yes, I have both the current versions of WP and SP.

and you are getting a tinymce not defined error?  not sure how that is possible…

as to the 999 error, did you confirm you werent running out of memory?  how big was the file being uploaded?

another possible cause for your server to stop responding is that the php temp upload directory is not defined.. can you verify it in your php.ini?

Hi,

I’m not that tech savvy so i don’t understand the second part of your response, but yes, the error I get says:

“tinymce is not defined
OlioFireSig-2.jpg: Error 999 – Unknown server error (check image size – may be exhausting memory)”

There is definitely enough memory on the server. it’s on a private server and I am way below my limits. I have tried it with other images, all very small standard banner images. 

I don’t understand the php temp upload directory possibility. Can you walk me through how to figure that out? If it helps I can email you a password so you can login yourself. Just don’t want to post it publicly.

Hi, am I looking at the right thing? That looks to be a discussion about the edit option not appearing. Mine appears, but it just wont let me upload an image. I can upload images in posts, just not in sigs. I get the mentioned error message. If it helps, I can use the sig, but I have to add html code and host the image elsewhere.

that link is the exactly the latest on it…  slight error in the file uploader (and core) prevents the file uploader from uploading an image in the signature profile form…  fixed in the upcoming 5.5. around end of month once Andy and I finish up with our travels this month…
