The problem about the script, you have to set a default template (delete the old's), language to english, delete all blocks, disable all modules (else system)
copy 2.0.13.2
execute the downgrade
Go to modules, update system, activate other modules (cbb need to copy xoops22 to Framework), update all modules, re-set the group permisons, clone a new template and set on,add blocks
upgrade to 2.0.14
Go to modules, update system
add all others thinks you want in this stage(theme,etc..).
