Adding logo, favicon, and meta-graph in xenforo are the few things that should be done as soon as your forum is ready.
Here are the simple steps to add a logo and favicon in the Xenforo forum.
Go to your Xenforo Admin Control Panel. Go to Appearance and click on Style properties.
Make sure you select the correct style for which you want to change the logo. You can upload different logos for different styles.
Once you select the desired style, go to the Basic options.
Now, under Basic options, you will find a section named Logo. You can upload your logos and favicons here. You can upload directly using the upload option or you can paste the URL of your logo.
As you can see, you can also upload jpg, gif, etc as a logo.
You can also change the default image upload path, though we will keep it as default. Click submit.
Set up the width and height of the logo. This is to avoid Cumulative Layout Shift (CLS).
Similarly, upload favicon and different icon asked.
You can generate all the required sizes from AppIconMaker. Just upload your main logo/icon and click generate and the website will design around 30 different-sized icons to use anywhere. Download the required size and upload them here.
Once done, click Save.
All done. Check your main forum, if you are not satisfied with the size of the logo, change the width and height until you get the required one.
Comment down for any issue you face.
