Is the plugins order important

Yes sir/madam, the plugins order is very important for MijoSEF.

To be more specific, the System type plugins order does affect MijoSEF's functionality. So this is the order that your System plugins should be ordered:

• Other plugins
• System - MijoSEF
• Cache plugins
