But I don't understand how to enter their php snippet under the PHP tab on the XF Page.
The PHP snippet I should enter is:
<?php $URL= ‘https://api.zotero.org/groups/mabinogistudy/items?format=bib&style=apa’?> <?php $var= file_get_contents($URL)?> <?php echo $var ?>
However I was unable to Copy the php snippet from the instruction as it was an image file.
Here it is.
