API Error: EspoCRM API is unavailable

[modified]

I keep getting this error:

API Error: EspoCRM API is unavailable.
Possible problems: disabled "mod_rewrite" in Apache server, disabled .htaccess support or RewriteBase issue.
Do only necessary steps. After each step check if the issue is solved.

None of the suggested fixes work. PHP configuration is all OK. I have tried with the last three versions of EspoCRM, up to the July 27, 2018 version.

Apparently the address to the API is wrong. What should the address be? What is the script getting? Is there an error log with more info somewhere? How do I troubleshoot this?


I am trying to install EspoCRM in a folder on an add-on domain on a VPS, like this:

website.com/crm

which is actually a rewritten (?) version via virtualhost and dns magic of:

website.maindomain.com/crm


I think the assumption is that you install EspoCRM in the www root (/var/www/html). Is there any way to get EspoCRM to work in a folder of an addon domain? What changes should I make?


I see this problem has been reported before, but I can't find a solution anywhere.

Thank you for your response tanya

I have tried many variations of the suggested solutions. Nothing fixes the problem and I can't tell if they have any effect.

Is there an error log anywhere that gives more clues about what goes wrong? The script can't find a file; which path does it need? Which path is it getting from my Apache configuration? etc.

Could you share your .htaccess and the current espo path?

[modified]

I've tried this in the /crm/api/v1/ .htaccess file:

RewriteBase /crm/api/v1/

And many variations... My full espo path is:

/home/accountname/public_html/mdfd/crm

[tanya]

the path to the webserver is /home/accountname/public_html or /home/accountname/public_html/mdfd?

The path to the webserver is /home/accountname/public_html

mdfd is an add-on domain. I am trying to install EspoCRM in a directory /crm in an add-on domain.

I have now installed EspoCRM without problems in /home/accountname/public_html/crm

But am still curious how to make installation work in a directory in an add-on domain.
