Frederick has solved this: Using line break removal for JavaScript caused the issue.

Users who are experiencing this issue need to be aware that it is still necessary to include ‘wp-content/uploads/imagerotator.swf’ in the rejected files field under CDN/Advanced, if using CDN with NextGEN Gallery Slideshow.

Still can’t get the Nextgen/options/general PicLens/CoolIris option to work, but that is not critical and probably just adds external bloat to the site.

Got no suggestions. Using W3 Total Cache. Had to do lots of homework to get this up and running, but the results are impressive!

Frederick- Thank you so much for taking the time to look into this- and solve it, and for building this impressive plugin!

Frederick- Yes, my WordPress installation is in network mode with MU Domain Mapping. W3TC is running on both sites (there are only 2 and each was activated separately) with no other issues- excellent performance boost on both sites. I have submitted a bug report.

@ Frederick Townes-

Your generosity in responding so promptly to the various inquiries about W3TC is impressive and surely appreciated by all, but I would like to respectfully suggest that you could save yourself and the users of this fabulous plugin LOTS of time by providing better basic documentation and installation instructions.

Having successfully setup W3TC with self-hosted CDN on 2 sites using WP 3.0 Multisite & Domain Mapping, clearly I have aptitude for this sort of thing, but very little experience with web/tech issues.

I had to consult various third party guides, with often conflicting information, for initial set-up, but there is lots of information out there about this.

Information about setting up self-hosted CDN was harder to find, and information about setting up self hosted CDN + multisite + domain mapping was like looking for a needle in a haystack.

It would be a huge help and time-saver for everyone to have a basic guide for non web-tech-heads that includes:

> Gathering information about your server
> Setting up self-hosted CDN

(Particularly the configuration panel- it took me forever to determine the correct information for the various fields, especially for FTP path, which in my case needed to be left blank in order to work!)

> Gathering information about your host/server
> Basic setup for various server/host types
> Basic setup – No CDN
> Basic setup – Self-hosted CDN
> How to create a subdomain in cPanel
> How to create an FTP account in cPanel
> NOT to use network activation in multisite
> Must be activated and configured on ALL sites!

I’ll bet that for every hour you might spend pulling all this information together in one place you will save yourself and your users multiple hours of time and effort!

Both sites are now successfully running W3 Total Cache with:

> Self-Hosted File Transfer Protocol Upload
> WordPress 3.0.1 multisite
> WordPress MU Domain Mapping

Multisite users of W3TC need to be aware that you will not see any performance improvement until the plugin is enabled and configured on ALL sites! I was initially disappointed to see no improvement after enabling and configuring my primary site. After setting up the 2nd site everything really popped! Speed and performance WAY up on BOTH sites! Very impressive!

@ Frederick- When you say “WordPress MU Domain Mapping is not fully supported right now” what exactly do you mean? It’s working beautifully for me right now on both sites (except for the unrelated NextGEN slideshow problem).

Thanks, Frederick. Will do a bug submission.

Frederick- There is no issue with my multisite, domain mapped configuration. The flash player works fine when W3TC is disabled. Nonetheless, the author is aware: https://www.ads-software.com/support/topic/plugin-nextgen-gallery-plugin-nextgen-gallery-slideshow-will-not-work-with-w3-total-cache-amp-cdn?replies=13

Frederick- Yes, still not resolved. I’ve tried including various files under CDN Rejected Files, such as ‘wp-content/uploads/imagerotator.swf’. This has worked for others, but not for me. Disabling CDN does not work either. This is not a MU issue, since disabling W3TC allows it to work.

OK, I’ve got w3TC set up with self-hosted CDN on the primary site. How do I configure the other site? Do I also set this up as self-hosted CDN with an additional subdomain?

Thanks, Alex! Still looking for a setting on W3TC that may be causing this. Maybe we can get some help from Frederick?!

Thanks, Alex! I would like to be able to use nextGEN, but it may be easier to install a different gallery plugin than to install a different caching plugin.
