has_cap was called with an argument…

Hi @josiah-s-carberry,

Have you tried de-activating your plugins, to see if that removes the error-message?
If it does, which I think it will, it has something to do with one of your plugins.

Try to narrow it down to which plugin exactly is causing this error – and then contact the developers.

I’ve seen this error before, and it has always been a plugin that was causing it ??

Yes, you’re right, Aris. I found the plugin concerned. Unfortunately, it is an abandoned plugin so any fix will have to be done by myself.

The problem now is to interpret the message “Usage of user levels is deprecated. Use capabilities instead.” How can I determine what deprecated functions concerns user levels?

I found the codex page that describes all the user levels, but I can’t a description of the functions that were used to manage those user levels

@josiah-s-carberry

Hmm, instead of starting to change the code by yourself, I would suggest using a new and maintained plugin like User Role Editor

I’ve used it quite some times, it′s easy, flexible and gets the job done ??

Best regards

Thanks for that tip, Aris.
I’m not sure that plugin will be of any use to me. The plugin causing my issue has nothing to do with managing user roles and capabilities. It has a completely different purpose, but it happens to make a call to that deprecated user level function. Unless the plugin you suggest filters that call and replaces it with a call to an equivalent capabilities function, it will not help me.
So, my question still stands. Where can I find a list of the deprecated user level functions?

@josiah-s-carberry

Ah I see.
Well, then I can’t help you, unfortunately.
I have no insight in the plugin what so ever.
I’ve found the same page in the coodex, as you mention above – but no further explenation.

I hope you find a fix ??

Yes, Aposentadorias.com.br, it is the same. If you learn how to resolve this, please share your solution.

Here is the solution I found and implemented:

The plugin has a call to the function add_options_page in which the third parameter was given as an integer. This integer needed to be replaced by the name of a capability, which are listed in https://codex.www.ads-software.com/Roles_and_Capabilities#Capabilities
