I made changes to the back to top button, specifically to add <span class="sr-only">Back to top</span> for screen readers. I added this span to > templates/t4_bs5_blank/language/en-GB/en-GB.tpl_t4_bs5_blank.ini :
T4_BACK_TO_TOP = "<a href='javascript:' id='back-to-top'><span class="sr-only">Back To Top</span><i class='fa fa-chevron-up'></i></a>"
It's not adding it on the frontend. I have cleared cache, I've visited the site from different browsers just to be sure it isn't a cache issue and the span tag is not being added.
Is there another place that I should be editing the back to top button?
Thank you for your help.
