Description of my issue:
I do not have a log file. I cannot open the administrator area after upgrading admin tools, akeeba and akeeba cms on production site. I know that I must test before do that but since now your upgrading works fine.
I obtain a white page in front and I cannot log in admin area because I have also a white page.
I try with a security copy of the same site and it works fine until I try to upgrading admin tools pro to the last version as mentioned in the component area of admin Tools. Now I have the same problem with my test local with all the same information and the same site as product site.
I try to correct the situation but I cannot .
The site is very huge, about 1.2 gig for the security copy made with the last version of Akeeba Backup Pro 4.0.2
Thank you in advance.

When I reinstall the old version (3.1) of admin tools pro all works fine. And for reinstalling that I must use the documentation of deactivate temporarily admin tools pro.
I do not know why these things happens when I upgrade the admin tools pro to the last version (3.2.1) the problem reappear.

There appears to be a problem with Admin Tools 3.2.1 and Joomla! 2.5.x. You will need to temporarily disable Admin Tools until Nicholas figures out a more elegant solution in the morning.

You can disable Admin Tools using the instructions here: https://www.akeebabackup.com/documentation/troubleshooter/atwafissues.html.
