The formatting of the popup dialogue is completely configurable by parameters in /application/config. These parameters are detailed in Documentation.
Who can make comments is controlled by both a page permission to view the dashboard toolbar and task permission to actually use the tool. Details are in the Documentation.
If you can see the dashboard toolbar, but are not seeing the Log Comment tool icon, the most likely reason is that you do not have the task permission for Make Log Comment.
On installation, the Administrators group are assigned this task permission.
Comments are like any other log entry. When viewing the log, just click the ellipses icon to the right and select to delete the comment entry.
There is no specific option for disabling the icon in the dashboard toolbar. To disable it you can do one of either:
What we mean here is an internal code exception in an addon or the core when you click the install button from the Add Functionality dashboard page or when you visit a page after installing an addon package.
If you experience such an issue, here are a few things you can check that may resolve the problem.
If you experience a code error on or immediately after install and need assistance, please use the Get Help link from the addon marketplace page to report the problem. On the Whoops report, click the [copy] button immediately below the error message. That will provide a stack trace you can paste into the help request and save time having to request that report later.
Perhaps you are unable to connect your site directly to the ConcreteCMS marketplace to install an addon or theme. This manual process works for all addons and themes - not just mine.
The process is exactly the same for addons and themes, except themes have an extra step of activating the theme after installing.
Sometimes step 3 above can run out of PHP execution time. This is most likely when installing an addon or theme that installs a large amount of sample content. You should not run into such an issue with any of my addons or themes.
If you do run into such issues, you can run the install manually from the shell command line.
$ concrete/bin/concrete5 c5:package-install my_package_handle
or
$ concrete/bin/concrete5 c5:package-update my_package_handle
When updating, be sure to replace the previously installed package directory rather than adding to it. If not, you could end up accumulating obsolete debris from a previous version of the package.
If you find yourself needing to install or update many addons or themes manually, consider my Package Magic addon. Once Package Magic is installed, through the marketplace or manually, all further installs can be handled from the site dashboard using Package Magic.
