Hi @wkkw,
Make sure you have updated to the latest Feed Them Social free version (currently 2.9.3), as a few issues have been resolved in this update.
For an IG Basic token, be sure that you have login credentials to the IG account and that it is public.
For an IG Business token, you need login credentials as well as the IG account be a business account and linked to a FB Business Page.
After you have gained a new access token, generated a new shortcode, replaced the old shortcode and after you update/publish, be sure to clear the FTS cache for the changes to take effect. You may also want to make sure to clear any caching plugins you have installed as well.
If you have gone through the above steps and are still having an issue, it’s possible that another plugin or theme may be interfering. Try deactivating all other plugins besides the Feed Them Social plugins temporarily. Then test to see if it works. If this works, try reactivating them, one by one, to see which one is causing the issue.
If deactivating all plugins doesn’t help the issue try switching themes to one of the default WordPress themes then look at the page (this can be done under the Appearance tab of your install). It’s possible the theme is causing errors.
