Q: I can't see any preview after installing this add-on.
A: Please check if your server has mod_security installed. If yes, make sure that proxy.php as rights to handle GET and POST requests. Otherwise this add-on and also XenForos build-in link and image proxy won't work.
Q: Why don't you use screenshot provider XYZ?
A: The providers included are very reliable quality screenshot providers with a solid history of business. We tried to include free options als well as paid options. Also a local installed option is available. We may include several other providers in the future, feel free to request the addition of the screenshot provider you like most.
Q: I have a problem installing the wkhtmltoimage package at my server, can you help me?
A: Sorry, we don't provide support for that kind of action. Please ask your server administrator or hosting provider for help. Generally you'll need a VPS or real server for the installation of any server software.
Q: I like to remove all cached preview files from my server, how can I do that?
A: Go into the option page of this add-on in Xenforo ACP, disable the master switch for URL previews and put "1" into the "Preview Cache Lifetime" field. This will delete all previews after the next daily cron has been run. You can run the cron manually to delete them immediatelly.
Q: I use the WordPress Screenshot Service but it seems that no screenshots are prepared and saved?
A: The WordPress Screenshot service features a very restrictive policy for providing screenshots. If you use them to much, they refuse the service for some time. We recommend to use Page2Images which provides 100 free screenshots a day, if you register at their account. Also additional screenshots are very affordable. If you have the need for an extremly high volume of screenshots, please consider installing wkhtmltoimage at your server to catch your shots yourself.
Q: I made a mistake and setup a preview size to large for my forum. Can I reduce their size without recreating them?
A: Unfortunatelly the size of the screenshot images cannot be changed once they are cached. You need to delete them (see FAQ above) and let the software do its magic in recreating them automatically if they are ever needed again.
Q: I want to style the external link interstitial screen?
A: Please make your modification in the "link_redirect" template which is a standard XenForo template and not part of this add-on.
General Error Handling after a faulty installation:
Q: My forum is broken after installing an addon. What should I do now?
A: Deinstall or deactivate the addon and ask for help. If you cannot reach the XenForo ACP any more, login to your web server and add the following piece of code to library/config.php:
Code:
$config['enableListeners'] = false;
This will disable all addons and enable you to get access to the ACP again where you will be able to deinstall the problematic addon.
