My site: www.thinkingoftravel.com is hosted with siteground.com and I am getting “Gateway Timeout 504” errors when I am saving as draft or publishing. The good people at Siteground have asked me to disable all plugins and do all sorts of things. Has not helped. Now (I think) they are blaming the theme in their latest update of the trouble ticket:
It seems that the plugin causing the issues is not the removed one. I have checked the server's logs once again and confirmed that the origin of the issue is not recorded. Please disable all plugins for testing purposes and check if the issue still persists. If yes, then I would recommend you to change the theme, because the theme is loaded even when you are working on the backend of the application. If the issue is resolved after disabling of the plugins, then you should activate them one by one in order to find the exact one that is generating the so slow process.
The people at Siteground suggests that I should change theme to avoid these errors. What is your view on the statement that the theme is causing this?
