Solution for wordpress Post image thumbnail 404 after change thumbnail size in setting – media
is Given Below:
I have some problems with media thumbnails in WordPress.
Default thumb old size is: 400×300
I created many posts with this thumb size. But for some reason, I changed thumbnail size in setting – media from 400×300 to 400×210.
after changing size, all posts not change thumb from 400×300 to 400×210 and can’t show images.
How to solve this or any plugins can fix it.
Thanks for All.
