问题
I'm using Joomla 3.8 to manage our community website (on the side pro bono). Everything was going well until I noticed an article with a padlock icon in the administration. I applied Global Check In, which unlocked the article. But now I find that I am unable to add or edit articles. Please see screenshot below:
The website is running on PHP version 5.6.31, with web server Apache.
How do I fix the problem? Is there any code I need to tweek?

This is how I determined the source of the problem. On the administration, I raised the error reporting to maximum: Global Configuration > Server tab > Error Reporting (changed from System Default to Maximum)
I saw the following errors: Notice: Undefined variable: plugin in */home5//public_html/plugins/system/connectdaily/connectdaily.php on line 42
Fatal error: Call to a member function logError() on null in /home5//public_html/plugins/system/connectdaily/connectdaily.php on line 42*
I deactivated the connectdaily plugin. The fix worked. I am now able to add and edit articles again.
I am still not sure where the connectdaily plugin is used for. If ever the website will need it, I will just reinstall the plugin.
