Error in php?

At the top of my blog I got the following message:

Deprecated: implode(): Passing glue string after array is deprecated. Swap the parameters in /customers/c/9/d/ on line 102

Is there anyone who has an idea of what I can do to fix this?

First please try to get these issues are resolved by getting in touch with your support author and if somehow you couldn’t get them as rectified or your author doesn’t reply then drop me an email via my author page. I will be your ultimate guide and will provide top notch solutions

Updating the theme to the last version should solve the problem.

Appearently I have the newest version of the theme. So I have to fix the problem in line 102 in a different manner. Any suggestions?

What’s the respond from the theme author?

You should change 2 variables to opposite side.

implode( var1, var2 ) to implode( var2, var1 ). It’s a PHP 7.x error.
