# 404 Error when using Sign-up shortcode

 * As you may have noticed by now, I’ve become a fan and contributor to your efforts.
   Love the PARTICIPANTS DATABASE plugin, although I’m having a problem.
 * When starting my test cycle for the form I’m planning, things seemed normal. 
   However, something has caused a derailment. I get:
 * 404 — Fancy meeting you here! …
 * This now happens when I press SUBMIT on a correctly completed form.
    It also 
   happens when I miss one or more of the required fields on the form. Submission
   and content checking both worked previously (although I’ve made form revisions
   since) and leaving out a required field generated the appropriate red box.
 * I tried trashing the page and creating a new one. I also tried deactivating and
   reactivating the Plugin.
 * The problem occurs under admin login, or anything less. I don’t take subscriptions
   to the site, and inputting the form may be a customer’s only use of the wordpress-
   based portion of my site.
 * In my setup, I do not send an email to the “subscriber”. Their input serves our
   editor as a source of database information that the editor manipulates thereafter.
   I use a child theme of RESPONSIVE that contains only simple CSS augmentations…
   these seemed to work before.
 * I’ll send email to you if you need URLs, etc…. Please just let me know.
 * Many thanks….

 * Have you tried re-saving your permalinks settings to rebuild permalinks?

 * Yes. My permalinks are set at default, and I re-saved. Can I show you anything
   that might “click” with you on the reason for the problem? Perhaps you could 
   go to it (bodyandsolwoman.com)and try the form to see what I mean….
 * Or – any other ideas?

 * OK, the usual reason for this is the page request is getting stopped by a security
   filter. This is put in place by your web host using an Apache module named “mod_security”
 * I suspect the word “request” (used in your submit button) is triggering it. Try
   removing that word and see if it helps.
 * If that doesn’t do it, contact your web host about the problem and ask them if
   mod_security might be blocking your POST requests.
 * This will have nothing to do with your theme or the CSS.

 * I tried your chage – took out the word “request” from both the button and the
   name of the page. Doesn’t seem to help.
 * I’ll contact my provider, NETWORK SOLUTIONS. But if it’s a problem with an APACHE
   module, I’m having trouble understanding why it worked previously, but stopped
   working. As if I did something in customization that caused it to stop working……
 * If you think of anything else, let me know. Meanwhile I’ll contact my guys….

 * There is no visible why it wouldn’t work. I know it’s in the POST array because
   the link is correct, but you get the 404 if you try the link with the POST request.
   That tells me the server is dong something different with that request behind
   the scenes.
 * The word “request” was just a guess because that could be considered a sensitive
   word…I didn’t see anything else that would trigger a security response. You web
   host will have a record of any security exceptions caused by your code.
 * I figured you changed the wording of the submit button and that’s what broke 
   it. What did you change between it working and not?

 * I can’t recall if I modified any other settings that might account for the problem.
   I think the easiest course of action will be for me to start from scratch. I 
   can certainly apply what I’ve retained in my notes about how I wanted to structure
   the database and such.
 * I’ll leave SUBMIT alone….. And double check for other possible problem wording.
 * I’ll drop another line when I’ve done these….please keep this open for the moment.
   I’ll be back!
 * Many thanks.

 * R:
 * I think I’m ALMOST home. I put my submit button back to its original setting 
   and cleaned up my submission form. I can fill out a sample form completely and
   send it, and get the listing into the database and the email notification of 
   new subscriber gets sent.
 * My one remaining problem seems to be error-checking. When I first installed plugin,
   failure to fill in a required field on the form resulted in that red-bordered
   box that listed the required fields left empty. NOW, if ANY required information
   is left off the form, I get the “404 message”.
 * I MISS the red box, and I’m afraid that exhibitors missing a required field will
   too!
 * Your thoughts?

 * I think I’ll need to see that. It’s probably the same thing…which I think we 
   never figured out. If you want to keep it private, send me a link by email: support

 * XNAU:
 * Thanks so much for not only your great plugin, but also for the thoughtful support
   you provided as we were working out the kinks.
 * With you input, I gave WordPress a “clean” installation and was able to get the
   plugin going just fine. Great answer to the needs we had. I also learned a lot
   more about how WordPress works.
 * Thanks again.
