I tried to update plugins and it also didn’t update. Then I found out that Akismet is not working as it was not connecting to their servers.
Googling didn’t help as it seems no one else has encountered this problem before.
After spending few minutes I finally solved this issue. It doesn’t too me long to figure out the solution.
I’m summarizing the issues followed by solution.
The solution is very simple and it will take less than 1 minute of time to fix.
However I’m not going to giveaway the solution for free. It will cost $100. If your WordPress site has same issues as I listed above and you want solution then contact me from comments below.
