Thanks for the heads-up @kevinvanscheijndel! ?? We really appreciate our users informing us (and other users) about compatibility issues.
In fact, we’re about to release a new version that warns about these incompatibilities. We divided the settings into two sections (same tabs: General and Advanced) but changed the placements of the settings and the new version will have a warning about the Advanced options which could potentially cause conflicts.
For now, you can try disabling the following options in SBP:
– Move scripts to footer
– Defer parsing of JS files
– Inline all CSS
Obviously, it’s not possible for us to handle every single plugin & theme in the WordPress ecosystem, but our roadmap already has items to make Speed Booster Pack more compatible with the most popular plugins & themes. With your warning, we added Divi to our list.
If you’re interested in our speed optimization services over at optimocha.com, we’d like to offer you a discount as a thank-you gift :).
