I have successfully installed SuiteCRM 7.10.25 and created users. However when selecting Activities->Emails I get the following error message:
Warning: count(): Parameter must be an array or an object that implements Countable in /srv/web/crm.edm-inc.com/htdocs/cache/smarty/templates_c/%%AF^AF1^AF13FE7B%%ListViewGeneric.tpl.php on line 45
This is just a warning message and it is not a fatal type error so It will not affect script execution. You can ignore this, it is showing you on screen because in your php.ini settings it is set as display_errors = on.
You can turn off by yourself or ask your hosting provider.
@aureh12 can you try deleting that cached file that is throwing the error? It will get re-created automatically. My hope is that this time it will be correct (if this bug has been fixed recently).
If that still doesn’t work, I would advise opening an issue for this on Github (if it isn’t already there).
