No Upgrade option

try Events > Settings > General > Admin Tools > click ‘Re-check Updates’ button then check again for new update at WP Plugins

In this case it was a dev version, so you’d click the button below it, however now we have v 5.4

in either case whether I click on ‘Re-check Updates’ or ‘Check Dev Versions” with ‘Enable Dev Versions’ checked ‘Yes’ I still don’t have the option to update to 5.4 in the plugins list. Strange? Any other suggestions or can I update manually?

try this guide for manual update – https://wp-events-plugin.com/documentation/installation/

we’re now on 5.4.1

sometimes after clicking those buttons you need to refresh your plugins page a few times for the plugin to appear
