Quote from jamespp2 on February 11, 2026, 19:48Hello. My filter buttons have recently stopped working on desktop chrome browser. Weirdly it is still working in Safari on my iOS devices. You can see this behavior on this page: https://hdgear.tv/equipment-catalog/?result=1&product_cat=zoom
I can click and unclick the filtering buttons, but nothing happens.
Thanks,
James

Just looked the site and javascript error appeared there
The issue is caused by LiteSpeed Cache JavaScript optimization. When LiteSpeed combines/minifies JS files, it's breaking WOOF's script dependencies.
Solution - Exclude WOOF scripts from JS optimization:
Go to LiteSpeed Cache → Page Optimization → JS Settings
In the JS Excludes field, add these script handles (one per line):
woof_front woof_checkbox_html_items woof_radio_html_items woof_select_html_items woof_mselect_html_itemsAlternatively, you can exclude by URL pattern. Add to JS Excludes: wp-content/plugins/woocommerce-products-filter/js/
After adding exclusions:
- Save settings
- Go to LiteSpeed Cache → Toolbox
- Click Purge All to clear cache
- Test your filters
Why this happens: WOOF loads multiple JavaScript files with specific dependencies. The function
woof_init_checkboxes()is defined incheckbox.jsbut the combined file either excludes it or loads it in wrong order.Alternative if exclusions don't work: Disable JS combination completely:
- Go to LiteSpeed Cache → Page Optimization → JS Settings
- Set JS Combine to OFF
- Purge cache and test
Let me know if this resolves the issue!

Looks like it was the issue in the plugin code - now its fixed, please update to the latest version and give us know how is it.
Note: do not forget to reset all types of caches after the plugin update

After the update the buttons are working again. However, I still have the issue of my first category not appearing. "Cameras" should be above "Lenses" on this page. https://hdgear.tv/equipment-catalog/
Thank you,
James

I could login into the site admin part, but I can not navigate there, each time I get
But I have time to see what category you mean "Cameras"
I have an idea that daata base need normalization: https://products-filter.com/how-to-fix-category-hierarchy-filtering-in-woocommerce-shop
Share ftp access to the site and will be good if you will add some more RAM to the site

Quote from jamespp2 on February 13, 2026, 18:51That is not the issue. Every camera has the category "Camera" and an appropriate sub-category "Digital Cinema, Broadcast, etc" assigned to it. You can also tell by the behavior on this page. https://hdgear.tv/equipment-catalog/?result=1&product_cat=cameras
