Wohaa.. I upgraded and my site is blank or white or...!!
 

Ok, when this happens it is most likely an addon that is not compatible with the new version.

Most addons should work just fine, there are a couple which might be problematic. These are the addons using EXIF information or the addons that require you to hack the PixelPost core files. Both things have changed dramatically in version 1.6, so be careful in using these addons.

Rename your addons folder through FTP. Name it something like addons_old. Then upload the addons folder from the Pixelpost install zip. Check if the site works. If it does, good, then it is indeed an addon. If it isn't: we made a mistake.

Now copy your addons back from the addons_old folder to the addons folder and recheck the site.

If it is white: there you have it. Start complaining to the author they need to upgrade their addons.

If it doesn't, great, this addon might be compatible. Continue this process until you have found all offending addons.

Thanks, I had the problem and resolved after seeing your post.

Very much appreciated.

It saved me loads of time...
