Start Scan button not showing

I have same problem. =(

I am facing the similar kind of issue. I tried on my website at Bonsai Plants Online ..

I can see this plugin is not updated for last 5 years.. Do we have any similar profiler plugin to use.

Hi,

I did a fix for this issue. There is a pull request for this: https://github.com/wpmudev/wp-p3-profiler/pull/8. Meanwhile you can download the plugin with the fix included from here: https://github.com/gabriel-munteanu/wp-p3-profiler/blob/master/p3-profiler.zip

I’ve released an update. Should be all good now thanks to @wyrda

Best regards,
Anton

Same here, using version 7.4.3 and wordpress 5.5.3, using the official version from gabriel-munteanu and the one provided by the author.
