I have uploaded 3 pictures successfully, and have been editing the descriptions -- then this error appeared:
Warning: Too many connections in /home/httpd/html/user_gallery/global.php on line 172

Warning: MySQL Connection Failed: Too many connections in /home/httpd/html/user_gallery/global.php on line 172
Error connecting to database.Error connecting to database.

Hope I wasn't the cause of this. I logged out, closed my browser, restarted it, logged back in, and now the same error appears when "User Gallery" is clicked.

 

This problem went away after about 20 min. last night. All is well.
