Error on startup when called for the second time

[kludikovsky]

Whenever I call phpMyAdmin from within T3 the second time I get the error:

Error
Unable to determine TYPO3_MODE.

This is regardless if I do a logout before or not (which in most cases I do following a timed out session)
When I manually delete the phpMyAdmin cookies the system can be called without any issue.

T3: 7.6.2
pMA: 5.1.4

Just for feeedback as i assume it has not yet been closed.

I still experience this still with
T3: 7.6.12
pMA: 5.1.8

But the workaround did not work now.

Is there any update on this?
It is now happening on all browsers I use (Op, FF, Vivaldi, Chr)
Just remoding the cookies does not help anymore.
And deleting all local data is not an option.

BY THE WAY:
The statements to check the BE_Mode:

if ( !defined('TYPO3_MODE') ) {
	die ('<h1>Error</h1><p>Unable to determine TYPO3_MODE.</p>');
} else {

are in all modules I visited at the very beginning (line 2) of the script. Not so with the PMA-Module, where they are at the end, following the class defintion and some statements. I am not deep enough in to judge this, but might this be a reason?

We will check and try to reproduce this issue since we were unable to reproduce it until now.
