Change your Osclass favicon directly from admin just by uploading a new favicon. All the steps about how to change Osclass favicon are presented in the plugin documentation page.
This plugin will allow you to upload a favicon and force the load of the new favicon on your site, without you clearing the cache if you chose to force load.
After you upload a new favicon, you need to clear your browser cache to see the changes.
For some themes, this plugin will not work because that theme has a favicon attribute set in the header. So is possible that you need to upload the favicon directly in the theme files.
What is favicon?
A favicon (short for ‘favorites icon’), are litle icons associated with a particular website or webpage, shown next to the site’s name in the URL bar of most browsers. The most common sizes for favicons are: 16×16, 32×32, 48×48, 64×64, 128×128. Browse to the file’s location on your computer to select the image and press “Upload Image” button to generate a favicon for your site
Once you have created your favicon.ico file, upload it to the root directory of your website and put the following code in the header of your html page (this should work with any type of web hosting plan o make your secure password): <link rel=”shortcut icon” href=”/favicon.ico” />
