since it is not occuring in your first example, this may not be the reason for your error.

You think upgrading to 4.4 release would fix it?

The upgrade looks a bit challenging because I do not have commandline access nor are the folder structures setup the same way.

Which is the version of qcodo and php?

P.S.:
I think is a php configuration problem, because I use a long time the 0.4.22 release with php 5.3.10 and not get this error.

Fatal error: ob_clean() [<a href='ref.outcontrol'>ref.outcontrol</a>]:
Cannot use output buffering in output buffering display handlers in
/home/content/93/10807193/html/my.site/qcodo/includes/qcodo/_core/error.inc.php on line 138

This is the code that is causing it to fail:

if (ob_get_length()) {
    $__exc_strRenderedPage = ob_get_contents();
    ob_clean();
}

It worked - mostly.

But with the QTextBox, it would return its Text as “" (or null?) every time I used a QServerAction to submit the form.

For example - (this is in QTextBoxBase.class.php, starting on line 174 - default text mode - this is included with framework and works):

default:
    $strToReturn = sprintf('<input type=“text” name=“%s” id=“%s” value=“' . $this->strFormat . '” %s%s />',
   $this->strControlId,
   $this->strControlId,
   QApplication::HtmlEntities($this->strText),
   $this->GetAttributes(),
   $strStyle);

This - does not work (removing the name property and its associated string):
default:
    $strToReturn = sprintf('<input type=“text” id=“%s” value=“' . $this->strFormat . '” %s%s />',
   $this->strControlId,
   QApplication::HtmlEntities($this->strText),
   $this->GetAttributes(),
   $strStyle);

I searched the assets/js/_core for getElementByName and didn't find it.  

Can you help me think of where to look/what might be causing this?

I created an admin QPM which is within CODEGEN that uses bootstrap puts style in the admin table, buttons, menu and let the responsive layout

Please help me.
