Hi,
The tagDiv Speed Booster works with our recommended plugins, with others plugins could cause incompatibility.
Try to deactivate it if you have other plugins active and see if this problem is still present.
Please let me know if you still got the issue afterwords.
Thanks

you likely have some conflict with a plugin, or your server may be slow. I’ve not seen this issue on our sites at all. You should try deactivating plugins to see which one is causing the flash of unstyled text, or something inserting CSS in the head that is causing a delay to load rest of page such as slow ad network, complex jetpack element, or whatever. The plugin has been very highly tested with the theme, the recommended plugins, and on hundreds of websites (thousands?) and works very well when everything plays nice.
Sorry I don’t have better suggestion, but that’s the best advice I have. I went through these issues in January when we moved to new server. Couple of crappy old plugins simply no longer worked with WP 3.9 at all, and was not a theme or speedbooster related issue.
I have just been through all my plugins and as soon as I activate speed booster the problem comes back. It’s definitely that plugin.
