Problem with a Prestashop 1.6.1.17 project left/right col

We are preparing the relaunch of a prestashop Webshop on the base of 1.6.1.17 For the data migration we use a module from the marketplace. Unfortunately after the use of that module we have some strange behavior in the new webshop. Its not longer possible to control the left column / right column visibility in our shop, and its also displayed in a wrong way. i think the migration tool crashed some data or something like that. the problem - we can not just go back to a fresh installation becouse we already had a lot of customations. so it must be found out whats wrong, and it must be possible to run the migration tool again and again, as the old shop is growing each day. so the error must get fixed, and also the migration tool must get fixed that this will not happen again. To show the problem: When click on preferences -> themes and there on advanced settings, there it should be possible to activate or deactivate the left and the right column for each site (like product detail, basket, category view and so on). but the list is weird without labels, look screenshot: [login to view URL] And on the website there is wrong visibility of the columns aswell, right column is complete deactivated but still on every page there is the css tag "show-left-column show-right-column" in the body. Check here: [login to view URL] Thats why the layout is completely crushed, for example here: [login to view URL] See Screenshot: [login to view URL] After that main problems are solved, i will need someone for further project assistant. Solve Prestashop Bugs, Solve CSS problems, modify modules and so on. We are looking for a stable and longer partnership. regards
