I have a file in the var/compiled folder, I make some edits to the file…(a tpl.php file) on the nex day the file is back to its original form…
I made the same modification to the original .tpl file and it's OK…
I tried emptying the cache…nothing…
what goes into the var/compiled folder ? ho to change those files?
Temporary files like combined is and CSS. Should not edit files in that Dir. They are auto-created.
Thanks.
I imaghine the compiled folder is autocreated (“compiled” from the original .tpl file)
Th file is a .tpl.php file, I found tyhe corresponding .tpl file and edited it, but It always get re-generated using old settings.
In particular it contains a parameter to calculate VAT and VAT codes that is always incorrect …
but why ???
I trhink I have solved the issue… 
i was editing a .tpl file in the storefront skin…but this addon works in the admin section, so I edited the right .tpl file in skins/basic/admin folder…
