Thanks for the prompt reply.
I can now access the Database. However, I don't use wordpress, it is a simple 5 pages site created from sratch.
I understand there are limits, but I'm puzzled on my simple site with a couple of SQL queries per page to reach 15000 queries in an hour.
I also checked other related forums to this and was told that there is no way for me to reach that much queries unless the limit is shared for all free users of 000webhost.
Is there a way to monitor number of queries? I made my own counter for queries, and it only reached 50 queries at most for an hour from my 30 students.
I plan to subscribe to upgrade once my site is stable.
Thanks for your help.
