Everything was fine a few days ago. I updated to the latest version a couple days after it came out. Everything worked fine. I didn't make any other changes, except for posting a news article (and people did add more chapters to their stories).

But, this morning I got an email saying that one of my members couldn't update 2 of her stories. This what she said:

I'm not very computer literate so it is probably my mistake.

Around 10:30/ 11:00 this morning, I logged on - I entered my penname and
password then I clicked Manage Stories, Add new chapters in the A Cold Day
in PC spot.  The submission rules screen popped up and I scrolled down and
began to fill in the information just like always.  I cut and pasted my
story from word I did not download where it says (Browse).  Then to make
sure the spacing was correct I clicked Preview and it deleted all of my
story and stayed on the submission rules screen.  Then I re-entered the
information and I clicked Add Story and it did the same thing.  It deleted
the work that I just entered.  So I went to send you an email on the site
and it did not go through.  It sent me an error message.
I am trying right now at 1:07 to re-enter my update and I just pressed Add
story and it didn't work.  I don't know why it isn't working, I'm doing
exactly what I did before, just this time it's not working.

I hope this helps you, thanks again for all of your help and your quick
response.

She also said that she couldn't send me an email (the form worked before). So I tried as well, and nope, it no longer works.

I tried to make a test account, it went through, but it didn't send the activation email.

I tried to have it re-send it, but nothing.

I was able to update my story, but I'm also the admin.

Edit: For some reason, mail can be sent again. I re-uploaded emailer.php and phpmailer_include.php, but I don't think that was it because I never did anything to them in the first place.

I made a test account

Username: Noname
Password: stWbKN7NnF

I still don't know if people can post, but I'll try it.

Edit 2: I was also able to post a new story under the test Account, so I'll contact my member and ask her to try again.

I did decide to get rid of the E-fiction contact page because I like mine better.
