fix custom script errors

my previous projects will show details on what we have, please review or ask for details. the script can be seen at [login to view URL] it is now at a point where it is not working 100% on the new server and it was on development server. there is a white bar at bottom which will show broken image links where preview thumbnails should be, also when adding new items to database, the admin panel has a setting for publish - ON or OFF, it will not allow me to change from the admin panel. when attempting, it displays the following error: Fatal error: Uncaught PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'dva_pet_strayed' in 'field list' in /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL] Stack trace: #0 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](123): PDOStatement->execute(Array) #1 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](576): crud->update(Array, 'maindb', '7') #2 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](152): updateDataIntoTable('maindb', Array, '7') #3 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](27): include_once('/home/zzxukdgt5...') #4 {main} thrown in /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL] on line 123 Fatal error: Uncaught PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'dva_pet_strayed' in 'field list' in /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL] Stack trace: #0 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](123): PDOStatement->execute(Array) #1 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](576): crud->update(Array, 'maindb', '7') #2 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](152): updateDataIntoTable('maindb', Array, '7') #3 /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL](27): include_once('/home/zzxukdgt5...') #4 {main} thrown in /home/zzxukdgt5qik/public_html/tracker/admin/[login to view URL] on line 123 (truncated, there is more to this error i can provide in chat)
