Hi, I’m having a really frustrating problem which I’ve spent days trying to fix. Basically I want to import data in CSV format into a Wordpress Custom Post Type. However, after importing the data I noticed when I’m logged IN to WordPress the posts archive isn’t displaying all the posts and some posts are duplicated on the next page. For example, the default amount of posts displayed per page for the Twenty Seventeen Theme is 10. If I import 15 posts, it will display a total of 15 posts, but it will displays posts 1 to 10 on page 1 and then posts 1 to 5 again on Page 2, so posts 11-15 are not displayed. However, if I logout of WordPress OR increase the number of posts to display in the ‘Reading’ settings to 15 then all the posts display correctly. The issue only occurs if I import data into the CPT not standard wordpress blog posts. However, after importing into the CPT it also effects the display of the standard WordPress Blog posts in the same way. This still happens when the Litespeed Cache plugin is de-activated and/or deleted. Things I’ve tried so far: A fresh install of WordPress De-activating all plugins and switching to Twenty Seventeen Theme Adding CPT manually via functions file and also by using the CPT UI plugin Tried 2 different Import plugins WP Awesome Import and WP All Import My host have been looking into this but have not yet been able to find anything on the server stack that could be causing the issue. They only thing they have noticed is the import plugin gives every post the same timestamp which MAY be part of the cause. I've also contacted the the developers of the WP All Import plugin and they say they have other customers that use Litespeed webserver with no issues. Also, they provided me with a sandbox server environment to test the import data with the same plugin and the issue doesn't occur there. Surely there must be many Wordpress users that have to batch import data into Wordpress using a plugin and are on a Litespeed server. So in desperation can anyone advise me as to what I could suggest my host check in their configuration or anything else I could check myself?.
