Repeatedly keeps me on login page

On clicking Login button it keeps me in on the login page. Neither goes to Dashboard nor shows any error messages.

Please suggest me if anyone knows the issue.
Thanks in advance.

Sometimes such a behavior can be seen, when the code is not able to successfully create a session. Do you get a session cookie from the server? Maybe also check the database table modx_session.

Does an error get added to the MODX error log (file core\cache\logs\error.log) when you try to log in?

I see my database is full. Is this the reason?
If so, how can I solve the issue?

Also please tell me how I can transfer this database into a new database because this has no space and I purchased a new one.

Thanks.

When I sort by size, I see the modx_session is bigger than 1GB.
Can I delete some session data from here to free up some space?

Yes, do that.

It’s a quite common issue that with certain server settings, the sessions don’t get deleted correctly and the size of the database table continuously grows.
Maybe take a look at this article from Mark:

Thanks a ton. After deleting the table it works fine.
