Old Updated site, can't create/edit elements

[JackGoa]

Hi, I have a site that has been updated since Joomla whenever. It runs Fabrik. Currently the site is completely up to date, Joomla 3.6.4 and Fabrik 3.5.1, most recent Github.

Whenever I click on an element to edit it or even try to create a new element, I get a 500 error. There is nothing in the server error logs either.

Any clues where I can look to try and troubleshoot this?

I set error reporting to maximum and got this:

Fatal error: Class 'JFormFieldText' not found in /var/www/vhosts/xx/administrator/components/com_fabrik/models/fields/textorwysiwyg.php on line 25

Ok I fixed this and this is how:

I usually update from Github using shell. wget the files from Github, unzip, rezip needed directorties, extract in root. So, I manually downloaded to pc, unzipped, rezipped, uploaded the zip, then extracted the files using the server's Plesk control panel, and voila. Fixed.

Must have been a misplaced or corrupt file.
