post title problem

Could you try to replace the 30 with ۳۰ in your post title?

A quick fix is to set the direction of post title to right to left. By default direction of post title is left to right. You can do it by using the following CSS code:

.post header h1 {
   direction: rtl;
}

Don’t edit the theme files directly, otherwise your changes will be overwritten whenever the theme is updated.

An easy way to add custom CSS is to install the Jetpack plugin and activate the Custom CSS module. You’ll then add your custom CSS in the new stylesheet editor that’ll appear in your dashboard, under Appearance > Edit CSS.

As alternatives, you could either install a standalone custom CSS plugin, or create a child theme.
