Thank you for the link. However, I am still getting the same error. I increased to 50 embedded media in post and the same error. Any other suggestion? Should I increase even more the number of media per post?

That error means that the replacement is resulting in an empty message which is not allowed. Or it could also be non-empty, but containing only a BB code with an invalid param (from a bad replacement) such that the post is effectively empty due to the invalid BB code.
Try running the replacement again without saving changes. Then review the replacements to look for errors or empty messages.
After 2 attempts following your last suggestion, I started to get some fatal errors:
ErrorException: Fatal Error: Maximum execution time of 30 seconds exceeded - library/XenForo/DataWriter/Discussion/Thread.php:142
and the second error message:
ErrorException: Fatal Error: Maximum execution time of 30 seconds exceeded - library/XenForo/BbCode/Formatter/Base.php:218
