If you have Installed Plugins or Themes before or after the x10hosting Migration then this could have caused the error to appear. You could disable plugin by plugin to see if the error removes or try installing a new theme and disabling the current installed ones... maybe this could work? You might have to wait for the Staff to respond but It could also be something to do with PHP from x10hosting side. I'm currently experiencing problems with my PHP WordPress blog. I'm unable to access my blog after the Migrations happened. You could also go to
/home/fscente2/public_html/digilabs.fr/wp-includes/option.php and find the line
302. I would suggest that copying all the current code inside
option.php to
pastebin.com then set the
Paste Exposure to Private and then submit. What does this do? It gives you numbers all down the side per line so you can hit F3 on your keyboard which should bring up a search box for your internet browser and then search 302 and It will locate to the line 302 with the current error you are experiencing. Then I would advise you to submit it here or privately with one of the staff members unless you are able to fix this problem yourself. I hope this managed to help you fix the problem but if not I'm sorry. I do not have much knowledge in PHP so I'm unable to help you fix this. SORRY!
