Ralf Skirr Posted November 22, 2012 Share Posted November 22, 2012 I want to upgrade from 1.5.0.17 (fresh installation) to 1.5.2.0. Module 1-click-upgrade is installed, the pre-Upgrade checklist is ok. Clicking 'upgrade prestashop now' results in this error message: Javascript error (parseJSON) detected for action "upgradeNow".Starting restoration... Then, obviously, the upgrade does not happen. How to fix this? Link to comment Share on other sites More sharing options...
Bodel Posted November 22, 2012 Share Posted November 22, 2012 (edited) Hello, I'm afraid I have some bad news for you. This bug was reported some time ago and as far as I know it still not resolved. http://forge.prestas.../browse/PNM-618 I can only suggest you to use 3-rd party service to upgrade your presta. It is paid, but it is currently the only solution I can find. Edited November 22, 2012 by Bodel (see edit history) Link to comment Share on other sites More sharing options...
