Images are not shown in the new version in my site.

Hello stackideas staffs,

Thank you very much for your supplying good products and support.

I have recently updated Easyblog to the latest version, 5.1.8.
I can't show images in the frond-end except the cover image in this version.
Images are not shown in old posts, too.
I can watch the images correctly in the back-end.

Please give me some advice to solve the problem.

Best,
Kenzo
