We recently found a issue with OptimizePress. While creating a page using OptimizePress, images were not seen even after inserted into live editor. We troubleshooted but didn’t get a way. After speaking to support we came know that OptimizePress has conflict with Avada theme. We were advised to deactivate fusion core plugin but that is not possible.
We are looking at other solutions. Meanwhile we didn’t find any issues while using OptimizePress with Rocket builder theme.
