# Jetpack 3.5.3 Upgrade Causing PHP Memory Allocation Errors

 * I applied the Jetpack update to around 60 websites, and 3 experienced problems
   afterward—two of which are using a customized child theme of iThemes Builder 
   Madison and the third using an Enfold child theme. One of the sites also has 
   an identical test site that works fine—the only difference being that Jetpack
   is not activated on the test site. All of our sites are on the same server using
   the same PHP configuration, and the majority are custom Builder child themes.
 * I temporarily deactivated Jetpack on all 3 sites, which solved the problems. 
   When Jetpack is activated, however, I experience memory allocation errors in 
   the back end (the front ends appear unaffected). On one site, these errors occur
   as I navigate to different sections of the back end such as the Plugins or Widgets
   page. On the other sites (one Madison child and the other Enfold child), a Fatal
   Error message appears in the WordPress News feed section of the Dashboard:
 * `Fatal Error: Allowed memory size of 67108864 bytes exhausted (tried to allocate
   287209 bytes) in ../public_html/wp-includes/wp-db.php on line 1219`
 * Jetpack appears to be artificially throttling the PHP memory, which the server
   reports as 256MB. All is fine when Jetpack is deactivated, but when activated,
   it’s like it reverts to 64MB (on these particular sites, anyway, which makes 
   me wonder if there’s a conflict between Jetpack and these specific themes).
 * I really need to get Jetpack reactivated on these sites again but want to make
   sure the conflict is resolved. Please let me know if you have any insights into
   this issue and what I can do to fix it. I can provide additional details if desired.
 * Thank you!
 * Melissa 🙂
