Error in Plugins Keywords Cloud Block and Language Toggle Block

Good morning.
I have the following errors in the plugins:

  • Keywords Cloud Block

It installs correctly, but the words appear distorted.
I have already changed the character pattern. But the error continued.

Collation: utf8mb4_0900_ai_ci
Charset: utf8mb4

Collation: utf8_general_ci
Charset: utf8

Plugin version: Release v1.1.1
Note: the website language is Portuguese (Brazil)

  • Language Toggle Block

When configuring and activating the plugin, I realized that not all words and articles are translated.

What application are you using?
I updated the ojs version: > > (current version)
PHP: PHP 7.3.13
MySQL: 8.0.25

Thank you all.
