This is why WebP generation from our side fails. [Here is an example image](https://mhmobil.de/wp-content/uploads/2024/11/Engcon-1-1024x336.jpeg.webp). * What refers to the speed, [there is an issue with Text Compression](https://pagespeed.web.dev/analysis/https-mhmobil-de/mln2emt68x?form_factor=mobile). Will you please kindly ask your hosting provider to enable Text Compression on their side and recheck the speed? * Regards, Mane * Thread Starter [mhabgeordnete](https://wordpress.org/support/users/mhabgeordnete/) * (@mhabgeordnete) * [1 year, 2 months ago](https://wordpress.org/support/topic/webp-ionos-apache2/#post-18369526) * Thank u very much, that worked! * Thread Starter [mhabgeordnete](https://wordpress.org/support/users/mhabgeordnete/) * (@mhabgeordnete) * [1 year, 2 months ago](https://wordpress.org/support/topic/webp-ionos-apache2/#post-18375738) * Unfortunately, I now have the same problem as the person in this post: [https://wordpress.org/support/topic/images-not-loading-in-home-page-until-interaction/](https://wordpress.org/support/topic/images-not-loading-in-home-page-until-interaction/) My gallery does not load directly in the mobile view, only after touching the mobile screen. * Plugin Support [Mane Grigoryan](https://wordpress.org/support/users/manegr/) * (@manegr) * [1 year, 2 months ago](https://wordpress.org/support/topic/webp-ionos-apache2/#post-18398445) * Dear [@mhabgeordnete](https://wordpress.org/support/users/mhabgeordnete/) , The delayed JS functionality you are experiencing is designed for speed optimization. It ensures that JS execution is triggered only on user scroll/tap, resulting in faster loading times. The element-rendering scripts won’t execute until prompted by actions from page visitors, so you need to tap/scroll first to get page elements. * As it is critical for a good website score, we would recommend leaving it in place, as users tend to start interacting with websites right away.  * However, you can disable the **JavaScript Delay** option anytime from the **Website Booster > Settings** section, which will allow the JS files to start loading right away. Please, note that the speed score will be negatively impacted. * Regards, Mane Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘WebP Ionos Apache2?’ is closed to new replies. * ![](https://ps.w.org/tenweb-speed-optimizer/assets/icon-256x256.png?rev=2753401) * [10Web Booster - Website speed optimization, Cache & Page Speed optimizer](https://wordpress.org/plugins/tenweb-speed-optimizer/) * [Frequently Asked Questions](https://wordpress.org/plugins/tenweb-speed-optimizer/#faq) * [Support Threads](https://wordpress.org/support/plugin/tenweb-speed-optimizer/) * [Active Topics](https://wordpress.org/support/plugin/tenweb-speed-optimizer/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/tenweb-speed-optimizer/unresolved/) * [Reviews](https://wordpress.org/support/plugin/tenweb-speed-optimizer/reviews/) * 5 replies * 2 participants * Last reply from: [Mane Grigoryan](https://wordpress.org/support/users/manegr/) * Last activity: [1 year, 2 months ago](https://wordpress.org/support/topic/webp-ionos-apache2/#post-18398445) * Status: resolved
