 * Hi,
 * The upgrade to WP 3.8.1 has been causing a great number of 500 errors on a website
   i manage. The errors come & go, it’s like someone is switching the lights on 
   and off. The website is quite a wide audience (4000 visitors per day / 20k pages).
   So these errors are very disruptive.
 * For the moment, i’ve done the following changes
 * – Increased MAX Memory to 128 MO
    – Disactivated some non essential plugins and
   essential plugins that have numerous “broken” reports betwwen their latest version
   and WordPress 3.8.1 (W3 Total Cache or WooCommerce for example).
 * The number of errors has fallen significantly but not completely. I’m wondering
   what my next step should be knowing :
 * – The theme was developed for WP 2.X (2.8 i believe). Could this be an issue ?
   –
   The website relies on quite à lot of plugins : A forum under Simple:Press, A 
   FAQ plugin, Akismet, JetPack, Contact Form 7, DMSGuestbook (don’t know why this
   was chosen), Wysija and a few more. I realize this could be the problem but things
   were working fine until a few days ago. Any insights on how to manage this issue?
 * Do you recommend i downgrade WP by installing an older version (3.7.1 or 3.8 
   for example) ? What precautions should it take if i go down that road ? The website
   database is pretty big (500 articles, 25K comments, 1000 forum threads for 5000
   messages. WP export feature is giving me crap. I’ve done a copy of the database
   but is there anything else i should be doing ?
 * Thanks for your help !
    Pierre
