Yes. Tomorrow I'll try to find out what cause this error "Class 'Joomla\\Utilities\\ArrayHelper'" It is basic Joomla class.

Fine.
Let’s keep in touch.

One question.
You use Joomla 3.2.5.
But current release it is 3.8.5

Why you don't use last version?
Probably, in previous releases, function, which I use to protect SQL-injection was not a function, probably was a procedure. And in this case I have to analyze versions and use different calls. Tomorrow I'll get your release and read more joomla documentation

I have a friend who's a programmer. He put the site online and, when I started customizing it, he told me not to update it to the last versions without asking him because he did something manually and was afraid the site could crash.
Now I ask him if it can be upodated

Hi Dima,
I can't see my website anymore, neither I display my adminitration panel page.
Are you doing somthing on it?

No. I didn't anything with your server and site.
I find out, that up to j.3.5.0 there was procedure (to protect SQL-injection), and from 3.5 - it is new function. I use function, therefore for your version of joomla I need to fix this. Today I'll fix my component and will give you new alpha-version to check. And if it will be OK, I'll prepare new release.
