[Release 4.0] Icons missing after upgrade from 3.x - Crisp Theme

I have updated today from 3.x to 4.0 version, but downgraded later since the button icons are missing. There are only rounded blocks but no icons are visible.

I use custom modified load.js file which uses "crisp" theme. The only change is there is the following.

addStyleFile('//cdnjs.cloudflare.com/ajax/libs/extjs/' + extjsVersion + '/classic/theme-crisp/resources/theme-crisp-all.css');
addScriptFile('//cdnjs.cloudflare.com/ajax/libs/extjs/' + extjsVersion + '/classic/theme-crisp/theme-crisp.js');
addStyleFile('//cdnjs.cloudflare.com/ajax/libs/extjs/' + extjsVersion + '/packages/charts/classic/crisp/resources/charts-all.css');

While default triton theme is used icons are visible.

Thanks

Revert this change and you should be good:

Thank you. Yes, I confirm that after reverting back this change theme is working back again.

Can you please tell me when it will be fixed permanently so I don't have to patch every time there is a new Traccar version?

It is already fixed.
