Is there a way to stop annoying popup?

I agree. This is awful – I’m on the hunt for a new slider!

It’s worse than you think – I have users who have author level access (and don’t have access to Master Slider) but it attempts to redirect them to the popup, then gets a 403 error. It basically stops them logging in.

A basic check to make sure the person was an admin before showing the nag popup would have been nice!

We are sorry hearing this. Can you confirm that you are using the latest version of Master Slider (3.3.4)?

Yes we have the latest version. My clients are finding it annoying that every time they sign in they see this pop up which takes them away from the dashboard that they want to view.
I’ve never known a free advert that does this.
I’m looking at Smart Slider 3 as a replacement since they are so annoyed and I can’t find a way to turn off the popup advert permanently.

This issue happened to a few number of clients having Master Slider 3.3.0 and Object cache enabled on their web server.
Most of plugins and themes (including Master Slider) use transient API for caching the remote or expensive process and rely on the cache data for a period of time. The problem is that while object cache is enabled on a web server, the cache will be stored in memory instead of the disk. As a result, depending on website traffic, the memory cache might be flushed earlier than expected expiration period or in such cases due to poor configurations on web server, the memory cache might be flushed after few seconds! Consequently, the above-mentioned processes will be triggered sooner and over and over again, which cause a lot more HTTP requests by the server to other services in the background.

So those who had this issue with Master Slider, be aware of this problem on your web server.

The quickest solutions for those who are using W3 Total Cache plugin is navigating to Performance > Object Cache menu under the admin menu and enabling the Store transients in database option.

Also we have almost finished providing a fix for this matter and will be available for download in few hours.

Thanks for your patience.

The new update released, please update to the new version and let us know the result.

Yes it works now. My clients still want me to change the slider.
