i get the following after the back end admin registration in joomla.

Error 0002 : Error has occured, contact your webmasterIncorrect data in 'blastchatc' table

I have tried everything in all the error 0002 topics I could find on the site. Delete the server re-register and so on.

Any ideas?

Fixed:

Go into mysql admin and open up your database.

Find the table jos_blastchatc

Search the fields and Edit the line with your server info.

Where it says URL put a www. infront of your website address.

This is completely incorrect!!!

You should never edit fields in database without proper understanding of those values you edit

Right now your private key is not aligned with your URL that you originally registered your client with. Your chat works only because last step in our security is not yet turned on, as it requires bit more testing, i.e. recreating security codes on fly using private and public keys, which in your case might create mismatch.

I recommend for you to do steps described in this topic My URL changed - chat stopped to work

Please, Can someone tell me how to fix this?

I get the exact same error. Blast chat worked once then was reinstalled and wont work since. I have created new blast chat accounts deleted the correct two database tables each reinstall.

What scares me is when I search for the error, dozens of webpages using the blastchat client are down with the same error.

All attempts by the admins to address this have been to reinstall.

I think something is storing the wrong data.

Maybe my cache? I have cleared the cache on joomla but Windows seems to keep filling in the wrong info for me.

*SMASHES WINDOWS* Argh I think windows cache needs cleaned like the prefetch folder!! AERGH!!

1. As you mention blastchat was reinstalled, crucial question is why? Why would you reinstall working thing?
(you upgraded your Joomla, you moved to new server, you changed your domain?)

2. If you followed instructions as you said you did (uninstall, delete blastchatc, blastchatc_users, delete your registration), then next blastchat installation is a completely new fresh installation like you never had it installed before.

I wrote it already few times but:

1. during installation:
- intra id is generated, private key is generated submited to blastchat server, previously transmitted and stored private key, intra id and URL is used to regenerate public key, security code; if any of that doe snot match, blastchat considers it as invalid request

Conclusion: Error 0002 is exactly error when blastchatc table has different information stored then what was transmitted to blastchat server during registration (which can happen if you changed your URL mosConfig_live_site variable, if you moved your site and created new database and installed blastchat client again, if you deleted blastchatc table and client re-generated those values)

Only help is to do completely fresh installation as described in topic "How to re-register my website"
