I added the 'define('QA_DB_RETRIEVE_QS_AS', 200);' line in 'qa-config.php'. After, I updated the "Length of Q&A page:" value to 100. But the number of questions on my homepage increased to 57. No matter how many times I set the 'Length of Q&A page' value, the number of questions on the homepage is 57 at the most.
When I do the same operations on my other q2a site, the maximum number of questions on the homepage is 72.
Why does this problem occur? What would you suggest for the solution?
