Usually, with this type of error it will be a misspelled function. What you’ll need to do is look at the function where it’s defined. Look at $this->, You will find that sometimes the variable has been improperly defined. Also, it may be that the programmer failed to define the method Instance Correctly. For Example, reusing Instance Methods, but failing to call on them properly. Methods are not stand alone. I would bet its one of these errors
