RE: The site is hosted on GoDaddy PHP version 5.
Which version of PHP 5? Connections requires at least 5.4. Connections should prevent itself from running on anything less than 5.4.
What version of Connections was being updated? I ask because the file generating the error in question has been part of Connections for awhile now, about 10 months. So it is a little odd to encounter the error now.
If you can send me an WP admin log and FTP login, as a private reply, I’ll take a look.
