Prestashop backend cache

[soduno]

I am developing some modules for Prestashop and having much trouble with javascript caching in the backend.

 

It dosen't matter if I clear cache in performance settings, or disable all javascript/file caching, the javascript file for the plugin is still getting cached. I have a local installation, and all the folders have 777 (to be sure), so write/delete should not be the case.

 

As it is right now, Prestashop has cached an typo-error in the javascript file that does that I cannot continue, because Prestashop won't let me edit the file, no matter how hard I refresh the site (clear caching in browser does not work either). If I open the javascript file directly (browser) it is showing the current version (without typo), so I guess that Prestashop is somehow forcing the cache...

 

I have experienced this in the past, but it helped clearing the cache(browser) but not this time, it seems. Any ideas?
