Error messages in SA 2

I have the latest SA2 version. I have tried replacing the file wavt_scripts_php.php, I have deletes cache, tried a few other things too but still get the following errors when trying to run SA2. I have two major projects which have ground to a halt. Is there anyone out there to help make this problem go away so I can get reliable use out of SA2? It all happens when I try changing eg a text area to checkbox group or list or any change. It also won't produce a checkbox group or even a checkbox.

Please refer my comments on the support ticket you have set up. It's urgent.

I have let our engineering team know you are awaiting a response.

As per your first post on the support ticket, Please can you make sure that it can be dealt with earliest today your time. ie. 7am as per your stated starting time. Thanks in anticipation. I am holding my breath.

Dani will not be in till 9am PST, I will ask him to make you his first priority though.

Are you sure it's not 10am that he gets to work? This is becoming an exercise in sheer frustration. I keep getting apologies from Dani for not getting back to me on past issues and now getting extremely angry. I have wasted so many hours waiting for Dani. It's now beyond a joke.

Please would you take a look at my recent support tickets. It is now after 10am your time and Dani is nowhere on the horizon. I am going home now but I would like a word with you management because it is now affecting business. So please can you arrange it. In the meantime, I will try and get hold of Ray early next week and see if he will kindly assist sort out the problems.
Thank you and good night.

I just spoke with Dani, he told me he has called you to look into the problem, and has found the issue is is currently working on a fix.

Thanks Jason. I got the fix but there are still problems which I have posted on the support ticket - plus images showing the problems. So I am hoping that these will be fixed pronto.
