Another experience upgrading TXP 4.6

gomedia · 2016-05-02 23:00:14

This morning I upgraded my local 4.6 installation to the latest GIT master zip.

At the risk of looking a complete wassak, I’m now presented with a blank screen after login. And PHP throws an error:

[Tue May 03 08:51:22.857592 2016] [:error] [pid 6473] [client fe80::b618:d1ff:feed:2453:49860] PHP Fatal error: Call to a member function start() on a non-object in /Users/adi/Sites/textpattern-git/textpattern/lib/txplib_db.php on line 395, referer: http://imac.local/~adi/textpattern-git/textpattern/index.php

Usual upgrade method – replaced the old files/folders with the new, then got the “Remora is dead, long live the new default” message, after that was blankety blank.

Any useful antidotes or even amusing anecdotes?

Hi Adi,

it looks like the global $trace is undefined or overwritten at some stage. Try to disable plugins by setting to 0 use_plugins and admin_side_plugins in txp_prefs.

Thanks Oleg, much obliged. It was one of my plugins causing the problem – not anything to do with $trace, I don’t think, but have yet to find out what.

I’d suspect an unfortunate extract() that rewrites the global $trace. We should give it a less common name.

$txp_trace?

Txp::get('\Textpattern\Trace') ? ;)

(I know this would require some refactoring)

+1, as long as it’s not called in live mode (or not at all)

Even better. Any takers?
