If you want to customize your Artisteer-generated WordPress Theme with Microthemer and you’ve changed the “art-” CSS prefix by following the instructions in this forum topic, you will find that the Blank Slate Micro Theme for Artisteer doesn’t target elements correctly.
Note: According to this forum thread, it isn’t always a good idea to do this.
If you chose simply to remove the “art-” CSS prefix, you can just download this Alternative Blank Artisteer Micro Theme kindly provided by Yiannis (remember to activate the alternative version once you’ve installed it!).
If you’ve used a custom CSS prefix e.g. “tvr-”, after installing the regular Blank Artisteer Micro Theme you will need to download config.json from the Theme Files table on Microthemer’s Manage Themes page and then do a Find and Replace All for “.art-” with “.tvr-” (for instance) and then another Find and Replace All for “#art-” with “#tvr-” (using Notepad or Dreamweaver or some other text editing program). You would then re-upload your amended config.json using the file upload button at the top of the Theme Files table.
