Joomsef with estate agent paid extension goes weel.
There is a problem with com_contact (a default joomla component).
It's the only component that returns a "500 error" when I try to send mail from site with rewrite or not rewrite url.
If joomsef plugin is disable in plugin management com_contact works.

500 - View not found [name, type, prefix]: contact,html,contentView

Thanks i had exactly the same issue with error500 when submitting the contact form. I had used the Beez template component override and it had the missing line

<input type="hidden" name="option" value="com_contact" />

from

<button class="button-validate" type="submit"><?php echo JText::_('Send'); ?></button>
<input type="hidden" name="option" value="com_contact" />
<input type="hidden" name="view" value="contact" />
<input type="hidden" name="id" value="<?php echo $this->contact->id; ?>" />
<input type="hidden" name="task" value="submit" />
<?php echo JHTML::_( 'form.token' ); ?>

In file
templates/(templatename)/html/com_contact/contact/default_form.php

Do a search for the other lines and you will find the lines of code and you can add the line in correctly as above

Thanks again
Ian
