Hi there,
I am experiencing this issue and after read some thread, I have tried to:
- Increase php memory limit
- Change the URL in settings to https (because is what I am using)
- contact siteground to remove the block: they told me that they have tried to change PHP version, fix permissions and disable the mod_security temporary for my domain but nothing of those resolved my issue.
Please I need some help or directions to know what to do next. Thanks
