| + | The footer fails to output for SNS themes, SM themes or other themes. | ||
| - | **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. | + | ==== Cause ==== |
