Extension Installer problem - Syntax Error: Unexpected Token

I'm trying to install a OpenPay extension in my OpenCart server.

At the beginning, I've got a lot of errors about folder permissions, which I fixed one by one by editing the admin/controller/marketplace/instal.php file, and adding them to the allowed array.

Now those errors are gone, but now I've got this error that is shown as a popup window (so I can't copy/paste it here) saying:
I'm attaching the image so you can see these errors.

All the files mentioned there as "No such file or directory in..." exists and they're are actually there.

I've noticed that the rename functions are incomplete, for example:
As you can see, there is no value after the comma.

I'm using OpenCart 3.0.3.1 and the OS is Linux.

Any help will be really appreciated!!

Contact the extension developer to resolved this issue.

Hello Sergiomng,
You have to check file where you have done changes, by mistake < this sign is left in file, remove this & your issue will resolve.

Syntax for renaming a file or folder is : rename(oldname, newname, context), context is optional, please once check the file which you are trying to replace exists or not and there is a permission issue i.e., while renaming is can't able to create new file and giving mkdir() no such file or directory. Please check that folder where you are trying to create new file / folder. Give permission to folder where you want to create new file/folder.

Note: If using Linux OS then check for file/folder permission. It should be 755 for applying any update in core files.

Thanks & Regards :
