In your template file you can use a conditional statement: if we are not on the no sidebar category, then display sidebar. You can set up a conditional statement by using is_category( ’18’ ): https://codex.ww.wp.xz.cn/Conditional_Tags
Thanks very much. Just for anyone else looking for a solution to this what i did was replace
<?php get_sidebars(); ?>
in single.php
with
<?php if (in_category('18'))
{
echo "";}
else
{
echo get_sidebar()
;}
?>
My PHP knowledge is next to none so i assume this sucks but it worked. I’m sure someone will have a more elegant solution.
sorry, didn’t mark resolved.
