 Well I have wordpress multi-site, one is on sub-domain.example.com and the
 other is on example.com/sub-folder.

 It's been going quite good! But suddenly I faced this problem today! The
 sub-domain wordpress is fine. But when today I was trying to publish an
 article on the sub-folder, it said HTTP Error and didn't publish the
 article neither did it save it as draft. To check whether the problem is
 on my server or wordpress, I quickly went to the sub-domain wordpress and
 tried to publish another article over there, but it didn't cause any
 problem. My Wordpress Memory limits are 96MB on both sites and max limit
 is 256M on both sites.

 What I must mention is when this error is given, the other wordpress site
 is also unavailable for a few seconds. And then both sites are back up and
 working.

 Also Note that I can edit previous articles and update them without any
 error. This problem is only happening in new article publishing time.

 The problems I was facing previously but didn't take any action because I
 thought the work is going on so let's not bother about it is, on the sub-
 folder site (current site which has current problem) used to show 500
 Internal Server Error whenever I published new article, the site stayed
 down for a couple of minutes and then when it is up and running, the new
 article was published! So when I saw that I found my articles published, I
 didn't bother to do anything about it. But now I have no other choice but
 to fix it.
