Hi,
I have gone checked your website from both sides (eng, Arabic). Yes, there are some content which is not translated yet.
There can be two things of this happening.
1st: you didn't translated the whole page.
2nd: If you have translated, but the cache problem.
Please, let me know if you are using WPML plugin for translation or any other plugin.
I am WP expert, and have extensive experience in Multilingual site development. I also review my calendar and I'm ready to get started immediately right away.
Let's jump on an initial 10-minutes chat, so that we can discuss your project in more detail and identify how my skillset will work best for you and provide immense value to your organization as well.
Best Regards,
Waqas!
