-====== Uninitialized PHP variables in injected blocks ======
+====== Footer fails 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 fails to output for SNS themes
-For example, for SNS themes: the footer template may fail to output due to the variable "$var_snstheme" actually being initialized in the header block.
+**Cause**:  The customized theme references user initialized global PHP variables in injected blocks. When those ESI blocks render, null pointer errors occur as those variables have been initialized earlier but the injected block has no way of recognizing them. In SNS themes, this is due to the variable "$var_snstheme" being initialized in the header block.
-Solution: Find the code where this variable is initialized copy this logic to the template of the injected block. For example, adding the following 2 lines:
