Same problem...trying to upgrade from version 1.3.9 to 1.5.0. I normally just hit the upgrade button and its automatic but now I'm getting the same error.

I wanted to upgrade the old to the latest version of the free component in tests. The automatic update failed. I had to manually uninstall the component, module and plugin because it has generated an error on the site and administration. There is a fix in progress? Thanks.

Any word on this? I tried to download the component but my six months expiration passed so now I would have to buy it again if I wanted to simply just upgrade like I was doing before. Please let me know.

So I got the latest version, followed the How to upgrade rules and now I get the error:
Fatal error: Class 'AcesefConfig' not found

I now can't access the front end or the backend of the site at all. How can I get back into it to try the installation again?

@Charles
Rename the /administrator/modules/mod_acesef_quickicons folder to anything else. Following the upgrade rules won't make up any issue, did you get any error message during upgrade?

@Tomasz
I've made the installation for you, check your ticket plz.
