We cannot create or edit articles in some sites, 3 of 25 sites, with Purity III, T3 Framework 2.2.6, Joomla 3.7.4. We noticed that after latest updates of Joomla and T3 Framework.
We found that if we unpublished the directory edit in
it works. This is of course not a correct solution but indicate that something is not OK with plugin.
We have uninstalled and installed the template and plugin but it will not solve the problem.
We hope the next update will solve the problem.
