PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
General	Add code samples for version compatibility checking to improve troubleshooting guidance Add code examples showing how to programmatically check WebDriver and browser versions to help users implement version compatibility checks. website_and_docs/content/documentation/webdriver/troubleshooting/errors/_index.en.md [160-164] ### Possible Solutions - Ensure the WebDriver version matches the browser version. For Chrome, check the browser version at `chrome://settings/help` and download the matching driver from [ChromeDriver Downloads](https://chromedriver.chromium.org/downloads). + ```python + from selenium import webdriver + driver = webdriver.Chrome() + print(f"Chrome Version: {driver.capabilities['browserVersion']}") + print(f"ChromeDriver Version: {driver.capabilities['chrome']['chromedriverVersion']}") + ``` - On macOS, go to **System Settings > Privacy & Security**, and allow the driver to run if blocked. - Verify the driver binary is executable (`chmod +x /path/to/driver` on Linux/macOS). Apply this suggestion Suggestion importance[1-10]: 7 Why: The code example provides practical, actionable guidance for users to programmatically verify version compatibility, which significantly enhances the troubleshooting documentation.	7
	Include system requirements verification in troubleshooting documentation to prevent compatibility issues Add a note about checking system requirements and browser compatibility matrix to help users proactively prevent version mismatch issues. website_and_docs/content/documentation/webdriver/troubleshooting/errors/_index.en.md [153-157] ### Likely Cause - The browser version and WebDriver version are incompatible (e.g., ChromeDriver v113 with Chrome v115). - macOS privacy settings may block the WebDriver from running. - The WebDriver binary is missing, inaccessible, or lacks the necessary execution permissions (e.g., on Linux/macOS, the driver file may not be executable). +- System requirements not met (check browser compatibility matrix and minimum system requirements). Apply this suggestion Suggestion importance[1-10]: 5 Why: Adding system requirements check is a helpful addition to the troubleshooting guide, though it's a minor enhancement to the already comprehensive list of likely causes.	5

Hi Sri,
I updated the content in other language files too.
Chinese - I added in Chinese language only.
For Ja & pt-br - The existing files are in English only. Hence added english version in those files.

Please review.

Thanks,
