Can't Preview in RW or Preview (Export) Mac or Chrome

Already sent an email to support but wondering if anyone else has seen this. Yesterday when I launched RW I upgraded to the latest release (Version 7.4 (18651b)). I am now getting the following error when trying to generate a preview either in RW or Safari or Chrome. This previously did not happen. Here is the error I’m getting:

Exception while exporting site

*** -[NSTaggedPointerString stringByAppendingString:]: nil argument

Yes, this is a known issue. See:

Just go back to 7.3.3.

Not sure how to do this. How do I revert?

You installed a beta version of RW. You must have the option in preferences set to be a beta user. If you’re not interested in beta testing turn that option off.

To roll back to previous release down load and install from here

Go to this address where you can download the version of RW that you want. Then, install the downloaded RW and start using it – instead of v.7.4.

BTW, if you don’t want RW to prompt you to install beta-versions, you can prevent that by unchecking the box in Preferences:

P.S. Doug just beat me to it…

Alternatively you can find all “old” versions here:

Thanks! I reverted to the previous version and am back in business! I was working on something where I really needed to preview it in RW and a browser.
