PHP phpMyAdmin error when trying to open

Question

I have free account on www.000webhost.com website. I had created database with 4 tables and uploaded some php files on file manager to use them as web services. It worked well for two weeks, but now it is not working well and gives me error, then I cleared the browser history and cookies but when I am trying to open phpmyadmin it gives me this error:

Error during session start; please check your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.

session_start(): open(SESSION_FILE, O_RDWR) failed: No space left on device (28)

How can I fix it, although the tables only contains 4 or 5 records only because I still test my work.

Answer 1

It seems it's temporary. On the Spanish-Foum of 000WebHost Community it's written that they know it:

There is known issue with phpMyAdmin you may get some odd errors popping up but the issue is being resolved.

session_start(): open(SESSION_FILE, O_RDWR) failed: No space left on device (28)

We are fixing it and sorry for any inconvenience; please do not create threads regarding it.

I have the same problem. Waiting for a solution by 000WebHost.
