Hi, after all this time, I picked up the server again to check the problem and for total happiness I managed to solve it! Remember, I'm using Ubuntu Server 16.04. I can not tell if it was by default from the beginning, but the 'VirtualHost' in the files "/etc/apache2/sites-available/000-default.conf" and "/etc/apache2/apache2.conf", was as below: <Directory "/var/www/html"> Options Indexes FollowSymLinks MultiViews AllowOverride FileInfo Require all granted </Directory> What I did was simply remove 'Indexes' and 'MultiViews', leaving only 'FollowSymLinks', as bellow: <Directory "/var/www/html"> Options FollowSymLinks AllowOverride FileInfo Require all granted </Directory> After that, I restarted the apache service and rewrite worked perfectly, causing my problem to be resolved as well, since it was being generated due to this incompatible Apache configuration with whmcs. Below I put the link that inspired me to make this change: I leave here my criticism of WHMCS support, as they have a deeper knowledge of Apache and the requirements of their system, could help us in this and save us great waste of time and great loads of stress. Anyway, thank you for all the help you have received. Thank you! Best Regards

That's it. I agree with everything you said brian! I've just been able to make the "Friendly URLs" feature work perfectly on a whmcs test facility made under a cPanel account. The case of the error of this topic, is about a new server dedicated exclusively to WHMCS. I have prepared a new ubuntu 16.04 (lcx) server for the whmcs strictly following the installation guide and pre requirements. The use of "BASIC URLS" will not be a big problem and we will start to use whmcs in this way, since we can not take risk in the production environment. What makes me more curious about this is the "why" of the whmcs support requesting ssh access to the server to later guide me to "get a server admin to check settings" Best regards

Many thanks for your help Brian! I opened a ticket, but the support did nothing more than say "it looks like the problem is on your server. So please let your administrator make sure there are no problems while reading url friendly" We can only wait. Thank you!

Hi Brian, thanks for your response. Really the problem seems to be the same as this post you recommended, because as soon as I changed the settings from "Friendly URLs" to "BASIC URLS", the problem disappeared. So does that mean I can not use "Full Friendly Rewrite" anymore? Thank you! Best Regards

Hi ChrisD, thank you for your response. I'll answer each question per line, okay? 1- Thanks to your question, I detected the following error in the browser console: "Failed to load resource: the server responded with a status of 404 (Not Found) /admin/search/client" Print: http://prntscr.com/irw29r. 2- I installed the admin theme of "swiftmodders.com" that we acquired through marketplace.whmcs.com. I opened a ticket with them, however they told me the problem is in whmcs. 3. The ticket ID is #TML-196961.

Note: Hello, I do not know if I can open a topic with a ticket for the same subject still open. However, I open this topic because it has been more than 28 hours since the ticket was opened and the problem still persists. The moderators of the community can correct me if this disrespects the rules. Hello all, recently I migrated our WHMCS from a cPanel panel to a Linux Ubuntu 16.04 (LXC) server. We fulfilled all the prerequisites and we were able to install the whmcs perfectly. The performance got much better. I checked the prerequisites and everything is correct at first. However, we are now experiencing a problem in which customers can not be selected during ticket opening. I made this print to demonstrate more accurately: http://prntscr.com/ir8n12 Anyone who has ever had this problem can help me? Thanks in advance. Best Regards
