Error on Xenforo 2.2.6 Patch 2 above

[thuylinh]

When I upgrade to version 2.2.6 Patch 2 or later I get the following error:

• Error: Macro admin:addon_list_macros :: addon_list_item_icon() error: Call to undefined method XF\Util\File::getImageMimeType()
• src/XF/AddOn/AddOn.php:373

This causes a lot of addons to lose their photos and errors when viewing the add-ons list. Please help me fix this.

Thanks you very much!

You have to verify if any complement incompatible with this version is that you are installing from xenforo

Either reupload the files, or upgrade to 2.2.7 as it seems some files didn't copy properly
