Save and get URL not working

[KelvinHong]

When I want to save some writings, an error occurs:

Post failed due to the following error:

Could not open /home/susam/www/mathb-content/59.txt for writing

This happens since two weeks ago and is still happening today, if I remember correctly. Seems like a server problem?

Having the same issue. Seems like this project is dead :(

This issue was occurring intermittently. The cause turned out to be insufficient disk space. The disk space has been cleaned up and this issue is now resolved.

@susam This tool is really helpful for me, thanks again for fixing this.
