As there is no one else reporting this problem I think it is a local issue.
Have you tried to disable all plugins besides Antispam Bee and switched to a standard theme (Twenty …)? Is the issue still there?
If not, you can enable everything step by step to see which is causing the problem.
You can check the browser console too, to see if there is JS conflict.
And you can enable the DEBUG mode of WordPress to see if there errors.
All the best,
Torsten
Thx Torsten, will try that and report back if I locate the conflicting plugin
