You 're welcome Reiyo,

Best of luck with your project.

Thank you very much Krikor

Well it seems like I still have the same problem no idea why I realized I can't save categories or articles I am not sure this is duo to a php extension or....?
no idea everything works on ipage and on my localhost but not working on imotion hosting!

Try disabling your extensions, one by one until you find the culprit.

I deleted everything and reuploaded files again this will be last try I uninstalled a few extensions that I expected they are causing the problems before I delete files and reupload again to server!
But now after files are uploaded there is an extension I am suspecting it is causing the trouble

I solved it
there was a plugin causing all these troubles

Which was it?

Plugin: "plg_searcher_k2"
Plug-in File: "searchertransaction"

I know it is not a part of the k2 core
The funny and strange thing is that every time I uploaded my files it seemed like the plugin code was on one line which kept causing the error Strange! Why this file among thousands of joomla files?

I wouldn't know.
I think you need to ask the extension's developer about this.
He might also provide a solution.

Yea me too I actually replaced it with original file checked the file and code wasn't on one line after replacement so it was uploaded properly! but still had the white page issue so I reported this to the extension developer ! and gave him ftp access he said he only replaced original file actually I just replaced it before him and nothing happened and he said code was on one line weird coz I checked the code after replacement and everything seemed fine

I 'm glad it had a good ending :)
