T3 framework and LiteSpeed cache plugin

catbusin

Hi,

There is some bug in T3 Framework (I think) when using Litespeed Cache plugin for Joomla! (https://www.litespeedtech.com/products/cache-plugins/joomla-acceleration/download)
Error "Class 'T3Path' not found" for some modules.
It happens in all JA templates that I've tested so I can't use this cache module on any of my client's sites using Joomlart templates. It is a great cache solution. The results are great so it would be nice to have a look and fix this bug.
I know that not all servers using LiteSpeed but there are many using it.

I've installed Mixstore demo just for testing purpose.
The LiteSpeed cache plugin is enabled at this moment. You can disable it from components > LiteSpeed Cache and options or disable the plugin.

I hope you can fix this.

Thanks
Regards

Hi Cosmin,

Is this the correct package to install? https://github.com/litespeedtech/lscache-joomla/blob/master/package/lscache-1.3.0.zip

Because I tried to install to a local site with JA Mixstore but it works fine, no error as on your site.

saguaros Hi

Yes, that is the latest release.
Did you enable the plugin?
In component options did you enable it?
Do you see x-litespeed-cache: hit in response headers (dev tools). If you dont see x-litespeed-cache: hit or x-litespeed-cache: miss, the plugin does not work.
And last question, do you have LiteSpeed server local? This is a server side cache solution for LiteSpeed servers only.
If you are on a LiteSpeed server you also have to add the following to the .htaccess file

<IfModule LiteSpeed>
CacheLookup on
</IfModule>

I've tested it on many JA Templates and the result is the same so that is why I think is a T3 problem.

Thanks

saguaros Hi,

I see that your server is nginx so you cannot test LiteSpeed cache plugin for joomla.
You can test it on demo site provided in private fields.
If you need something else please let me know.

Here are some useful links
https://www.litespeedtech.com/products/cache-plugins/joomla-acceleration
https://blog.litespeedtech.com/2018/06/12/beginners-guide-to-litespeed-cache-for-joomla/

For testing if LIteSpeed cache for Joomla! is working see the attached screenshot
In mozilla go to dev tools, network tab, select HTML and then select the first document (the page that you are on) and in the right panel, in header response you should see "x-litespeed-cache: hit" if the page was served from cache or "x-litespeed-cache: miss" if the page was not served from cache.
If you don't see "x-litespeed-cache: ..." then the plugin isn't working.

Thanks

I found out that Cart module and login module positioned in off canvas gives the error. If I disable them the page renders ok but off canvas gives the same error.... so if I disabel also the off canvas from template settings everything is ok so maybe has to do with off canvas but also with these 2 modules.

I have this cache plugin installed on other sites with other templates and it is working fine.
I've also activated the plugin on a fresh Joomla! protostar template with virtuemart and everything works fine. See the link http://vm.fusionnetwork.net/

Hope it helps.

Hi,

You can try with this tweak:

Backup this file: /plugins/system/t3/t3.php
Remove comment line 74 to 77 like this: http://prntscr.com/nquogp

Then clear all caches.

saguaros Hi,

I've commented those lines, on frontend everything works but in backend when try to edit template throws error "Error: Class 'T3Path' not found: Class 'T3Path' not found" with blank page.

See the attachments.

Thanks

Hi,

Sorry for late response.

I've updated t3.php file with the one provided by you and it seems that everything is ok.
The changes will be added in the next release of T3 Framework?

Thanks for quick solution.

I'm closing this thread now.

Have a nice day!!!
