Observed a month ago this issue but did not pay much attention.
Decided to fix it recently, not sure what causes it only on that category.
Here linkHardware Advice to it.
The category have there 40 posts they are totaling to 200 with this issue by repeating five times.
Also i have some codes in functions,php file which i added also based on GP support team, you can look my recent topics to see if they can cause some conflict.
Hi Leo, will try.
Some additional info.
The posts repeat each 25 posts starting from Heat Gun Preheat Idea to Alignment of the IC Chip in 4 steps, this happens 5 times which totals to 125, i was wrong on the previous info.
Also if i m on this category and press Customize the posts load normally 40 total without any repeat.
I only went and Activated the standard GP theme, cause Child one was Active, but it does same.
It seems now it does this x6 times not sure why, maybe i did not count proper initially.
When i press CTRL + F5 in browser to search a post it shows 12 finds of similar posts 6 are visible but 6 are hidden.
Hope this helps to detect the issue.
Not sure how but the issue is gone, i only went and enabled 2021 Theme plus have disabled most of plugins including GP premium.
I feel someone is playing with my site remotely, or it was a glitch.
Case solved for the moment, thanks.
