Hello @abeerjalil,
We investigated the report and found the issue to be caused by one of the SiteGround Optimizer’s Frontend optimizations called “Defer Render-blocking“. When enabled this caused the slider on the frontend to go blank due to a conflict with another plugin or your template.
We disabled this option and you can again activate the plugin in order to take benefit from all additional enhancements that it provides for your website.
Of course, we advise you to enable all optimizations with caution and inspect your website after turning them on. Some plugins may already apply the same optimization techniques which could lead to a conflict. In such a scenario, you can keep the “problematic” option disabled.
If you plan on using the SiteGround Optimizer plugin only for the sake of purging your website’s dynamic cache, you can do the same from your Site tools > Speed > Caching > Dynamic cache > Actions > Flush cache.
Best regards,
Georgi Ganchev
