-====== Uninitialized PHP variables in injected blocks ======
+====== Footer failed to output for SNS themes ======
-Some customized themes may reference user initialized global PHP variables in injected blocks. When those ESI blocks render, null pointer errors will occur as those variables may have been initialized earlier but the injected block has no way of recognizing them.
+**Problem**: The footer failed to output for SNS themes
-For example, for SNS themes: the footer template may fail to output due to the variable "$var_snstheme" actually being initialized in the header block.

-Alternatively you can remove footer block injection. This however will slow down page loading time as well as increase cache size and is hence not recommended.
