Your hosting/server data disk is full. Check the disk space limits.

my plan is unlimited hosting ? is there anything else or only that issue?

There is nothing called unlimited.

Even unlimited plans have limit.

They have restrictions on inodes (num of files).

Check your cpanel.

dont have deep knowledge in to this, i was saying the same thing what they said to me exactly ( unlimited website hosting and unlimited disk space), i never asked then about "inodes".
Anyway in this case i need to upgrade my plan right? or is there any other way?

According to the error, seems like that the limit problem pulls a chain reaction over the other files. If the website was working fine previously, the best solution will be to contact the hosting support and I am pretty sure that they will be more than happy to help you fix the problem.

yeah it was working properly previously, i did check with them they did delete some cache or something it worked well and again after 2 days the same error was coming, this time they were saying that i need to upgrade my plan. So, just to confirm its the same issue i am checking with you guys. Seems like I need upgrade now

Sometimes the error come if tmp is getting full. Also, remember unlimited space doesn't exist in the real world. So, contact with your provider and ask their help for solving the issue.
