Sorry – should also have noted the following:
WordPress 4.2.2
W3 Total Cache 0.9.4.1

popups not working anymore on client’s site here as well:
https://andersondentaldds.com

using Version 1.8.10

I am not using a CDN service. I disabled all but the following on the General Settings page and Meta Slider is still working fine:
Enable Google Page Speed dashboard widget
Use single network configuration file for all sites
Hide performance settings
Verify rewrite rules

WP Super Cache is a great product also – glad you found a combo that works for you!

probably a dumb question, but did you empty all caches?

Hi pbsbluejay, I have a multi-site that is using both Meta Slider and W3 Total Cache, and I am not having any problems. I also have minify enabled. The versions I am using are: Meta Slider v3.3.1, W3 Total Cache v0.9.4.1, and also WordPress v4.1.1. A page that has both running can be viewed here:

Not sure if any of this helps, but I know when tracking down a bug, all info is good info!

Well this is strange. I went into the general settings to set things up like I normally do and now it works. I have a feeling it was most likely setting Permalinks to Post Name that fixed things. This is what I changed:

General Settings –
Timezone: Denver
Week starts on: Sunday

Discussion –
deselected Allow link notifications
deselected Allow people to post comments

Permalinks –
set to Post Name
