Upgrading And Rollback Problems

[Adsantec]

      Hello,

           Until recently, we were running Prestashop 1.5.1.0 without issue, but after our webhost rolled out a forced PHP update, our website started generating errors and many functions were broken. After receiving little help from them, I attempted to update prestashop to 1.6.1.3, which eliminated the errors, but left our website in worse shape by re-positioning all modules at the bottom of the page which required excessive scrolling just to view. I was unable to move them into place either through hooks or through live-edit, and after struggling with the problem, eventually rolled back to 1.5.1.0. Now, despite the fact that I've re-enabled the store, and have re-enabled the webservice, the website seems to be stuck in maintenance mode! It is not a browser cache issue, as I was able to get the same result on my smartphone, which had never previously been used to browse the site. This leaves me with two questions:

 

1)  What other steps are required to get the website active again, aside from enabling the shop and enabling webservice? (No the multi-shop function is not used)

 

2)  How can I maintain the module positions from Prestashop 1.5.1.0 when upgrading to 1.6.1.3? I also tried an upgrade to 1.5.6.3 but the issue remains the same.

 

 

On a positive note, I did confirm that the new prestashop versions work with the newer PHP our webhost has forced upon us, so if somebody knows how to retain the module positions then the upgrade would be the solution. Being stuck in maintenance mode only appears to occur when rolling back to 1.5.1.0.

 

Thanks in Advance for the help.
