After updating to the newest version of Wordpress, my whole website layout changed and the Dendrite theme didn't function anymore, luckily I had made a backup just before the update. When I installed the backup and an older version of Wordpress I managed to get my website layout and functionality back. But when I want to make a change to the website or add a new portfolio page, I get the message connection lost saving has been disabled until you're reconnected. At the same time I get a message that there is a time out for the mail server. and it's also impossible to reach my website because the server can't be reached. This happens on all my devices, computers & mobile phones. But when I get out of my network by switching my mobile phone from wifi to 4G, I can reach te website and it functions like it should. So I thought the problem was with my own network, But when I tried to make changes on my website at a different location with a different network atctsactly the same problem occurred, with the website. I already tried different versions of Wordpress and different versions of plugins all with the same result.. my website currently runs on WordPress 5.4.4 with the Dendrite theme, and the plugins; Slider Revolution 5.4.7.3, and WPBakery Page Builder 6.5.0, Advanced Custom Fields 5.9.4, LiteSpeed Cache 3.6.1
