Because this is a functioning corporate website, I can’t do this for you. But I have lots of info for you, so perhaps you’ll be able to use this to find a solution.
Some background: While determining what was happening, and waiting for responses from all three plugins in play, our site had a blank home page for approximately 30 hours. (I’m not complaining about your speed at all – I still haven’t heard from the developers of the other plugins, lol – just that in the corporate world, it’s not okay to be down that long.)
Troubleshooting: Since I upgraded the PHP version in order to install your plugin, there was some question about which caused the other plugins to fail.
We pulled back the PHP version update, restored the site, then updated PHP again. All was well.
When I installed Landing Pages again, the same failure occurred. This time, it was clear what caused it.
The plugins affected are:
Icon Box WordPress plugin
LayerSlider WP
These operate the slideshow that’s the centerpiece of our homepage, and the scrolling box of client logos in the left sidebar. (You can see these at: https://www.1stbasis.com )
Both plugins worked before I installed Landing Pages, and failed only while it was installed. Now that it’s uninstalled, they’re working again.
I hope this is helpful, and that a solution is possible. Your functionality appears to be the finest out there, and I want to use it on my site if a fix can be found before I have to choose a different plugin in order to meet my deadline for AB testing related to a new product roll-out.
Thanks in advance for anything you can do to fix the conflict between these plugins.
