The YorkBirding website works well using the Chrome browser on Windows 7 and 10. It is also functional using Safari and Firefox on newer versions of Mac OS; definitely works with v10.14. However, some issues have been noted on other technologies:
Minor issue using the Edge browser – the Twitter feed scroll bar is not visible, however the Tweets can be scrolled using a mouse wheel.
Internet Explorer 11 – The Twitter timeline does not display, however the link works to take you to @Yorkbirding where you can see the history.
Mac OS v9 – There are issues with the menu and the display of the new-style gallery (as used for 2019 photo competition, sorry the old-style gallery is not compatible with the latest WordPress) using old versions of Mac OS and Safari. Suggest trying a different browser.
Samsung browser on phones – the menu is difficult to use, try using Chrome on the same device.
