2.5 Main Menu issues

New issue, maybe related. When saving a K2 item or category, the screen defaults to /index.php and a blank page. I then go back to display the page and then click cancel. The changes are saved but two step process.

Joomla cache is off and T3 cleared but same issue. Whenever I save a new K2 article or category or edit some existing ones I get a blank page after selecting save or save and done in the backend.
When I use the browsers back button and click cancel I get to the list view. If I reopen the item the changes are shown as they were saved. Obviously something wrong in my setup but no idea where to start looking.

Anyone…Any suggestions. Checked permissions and configurations but still get the blank page on save. Strange thing is it does save. SEO settings are on so maybe something there. Since the site is live I don’t want to mess with turning off and on unless necessary.

The only error that shows repeatedly in the logs is
/administrator/components/com_finder/helpers/indexer/parser/html.php on line 33
[15-Jun-2012 11:08:37] PHP Fatal error: Call to undefined function iconv() in /

The section referenced is

protected function process($input)
{
// Strip invalid UTF-8 characters.
$input = iconv(“utf-8”, “utf-8//IGNORE”, $input);

// Strip all script tags.
$input = preg_replace(‘#<script[^>]*>.*?</script>#si’, ‘ ‘, $input);

Not sure if this is related or if someone can recommend a solution.

Problem was solved via a PHP upgrade and recompiling the php across the site to include the iconv module. :D.
