This thread is resolved. Here is a description of the problem and solution.
Problem: I am using the Divi theme (everything updated) and the link to "older entries" does not work on the divi blog module. I have isolates the issue which only occurs when my WPML-Multilingual-CMS-plugin is activated.
Solution: Going to Dashboard → WPML → Settings → Post Types Translation and selecting the Translatable - only show translated items option for both Posts and Pages will make the blog page go back to normal.
This is the technical support forum for WPML - the multilingual WordPress plugin.
