PHP Script Correction

I have a small php script which is generating an error ever since the script was moved to a different server. The error occurs in the admin panel when a record is modified or saved, and when the user logs out from admin panel. (Attached are pictures of the errors) The record structure is simple, but includes an image upload. I need someone to: - either repair the script, review and correct the commands written on save / update. If the error is due to wrong permissions on folder or referencing files in wrong places, to correct the referencing. - or create a new form (following the same design as the current form) that would do the job. Please specify how much time is needed to correct the script.
