I get the following message on a website "Application error: a client-side exception has occurred" with macOS Catalina

...Please excuse my lack of knowledge, but I don't want to do something I'll be sorry for afterwards so hopefully you can advise me. If I clear ALL history does it mean I have to make-up new passwords for the many I have now to enter different websites? That could be a huge amount of work. I'm not sure if the cookies function to retain our passwords, or not. (I'm assuming the cookies are stored elsewhere and not just in "history.")Thank you in advance for any suggestions you might have.

No, clearing the browser history does not wipe any passwords that you have created and saved for websites. Clearing the cache and history is one way to eliminate certain browser problems, and is generally benign. You won't have to spend time re-creating passwords and such.

Browser history retains certain info (usually non-critical) about which sites you have visited in the past, including some cache and user/customer info. Passwords are not retained in cookies.

You can rest assured, my friend. 🙂👍🏽

If you do not want to clear all website data...

Go to Safari > Preferences > select the Privacy tab > click on Manage Website Data... scroll down and Remove only Walmart.

Another thing you could try is using a different browser:

https://www.mozilla.org/en-US/firefox/new/

It looks like the mainline version of Firefox (118.0.2) runs on Catalina – which means that Firefox for Catalina has been updated a lot more recently than Safari for Catalina has been.

If there are Web sites that don't work quite right with Catalina's version of Safari, or that complain about it being insecure, you might find it useful to have Firefox on hand for visiting those Web sites. Whether you make it your default browser or not.

Clearing Cookies:

As you visit sites, cookies will be used remember site-entered data such as passwords and names. On a private tab, all will then be deleted once the tab is closed.

Clearing your Temporary Internet Files:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
