Cant add downloads to basket in Firefox / Edge

Am logged in to site as customer.

You can add downloads to basket from the product category page - see https://www.anythinglefthanded.co.uk/e-books
- but (at least on Firefox & Edge) you are unable to add to cart on the specific download page - for example - https://www.anythinglefthanded.co.uk/he ... d-download. If you click the add to cart button on the product page, nothing happens - looks like the add to cart button is just part of a greyed out block

Only affects downloads - "normal" items can be purchased either way.
Items are in stock, enabled, etc
Running OC3.03.2 with apparel theme

No related errors in OC errors file

Only error showing on server logs is 2024-02-04 05:33:25 UTC [apache][authz_core:error] [pid 63909] [client xxx] AH01630: client denied by server configuration: /home/customer/www/anythinglefthanded.co.uk/public_html/ads.txt

Issue at least in Firefox & Edge but Chrome seems to be working (at least on mobile)!

Any suggestions to help fix please?

The issue is caused by your element <div class="row footer_block"> which covers almost the whole page with its height and width. Perhaps a corrupted stylesheet, or a corrupted product description?

Only affecting downloads - so had to be in the product description
Found the issue using code view - a load of extraneous code was included after the product text. Now removed and all working fine .
Thanks for your help
Marked as solved

Yeah, never copy/paste from a MS Word document because of all the dirty markup, always use Ctrl-Shift-v to paste into the description.

Now that it is solved, please add '[SOLVED]' to the beginning of the original forum thread title.
