Try this instead. From your server console, run "ulx debuginfo"
It will create a file, and tell you where it went.
Attach the file to your next post by clicking "Additional Options" below the text post window when replying.
Also, since I don't recognize many of those addons, try this.
Go to your gmod folder. Instead of actually going into the addons folder, right click "addons", choose search from the menu that appears.
A search window should open.
Depending on what version, and how you have Windows set up, you should find an option to search for actual text in a file, not just a filename.
This option may be under "advanced" or "more options"
Use the 'text in file' option to search for "PlayerSay" - use the quotes.
Tell us what of those addon folders it finds that in.
