Form bombing out in SQL

On Joomla 1.5 I made a simple form with just an email field and used that as the from name and from email. The form displays properly. When I hit submit, I get the "Thank you" message I created, but I never get the email. Here is the debug/error message:

Form passed first SPAM check OK 
Form passed the submissions limit (if enabled) OK 
Form passed the Image verification (if enabled) OK 
Form passed the server side validation (if enabled) OK 
Form passed the plugins step (if enabled) OK 
Emails data loaded OK 
Form passed all before email code evaluation OK 
An email has been SENT successfully from (test@test.net)text_1 to test@test.net 
Debug End 
Error 
Error loading Modules:MySQL server has gone away SQL=SELECT id, title, module, position, content, showtitle, control, params FROM jos_modules AS m LEFT JOIN jos_modules_menu AS mm ON mm.moduleid = m.id WHERE m.published = 1 AND m.access <= 0 AND m.client_id = 0 AND ( mm.menuid = 0 OR mm.menuid = 0 ) ORDER BY position, ordering 

Of course, in the place of [email]test@test.net[/email] is my real working email😛 Any help would be greatly appreciated!Thanks!

Thanks!

Hi Mary,

These two things could be related - or they might be separate problems.

For the email - are you using different From & To addresses? Can you send an email fromelsewhere on your site?

For the database - what host are you on? (I recall a similar problem before - see this thread.
