Title: Theme installation errors Last modified: August 19, 2016 --- # Theme installation errors * [anzarch](https://wordpress.org/support/users/anzarch/) * (@anzarch) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/) * Hey there, * I’m new to WP. My server had it installed for me, and I’m trying to set up a new theme. I’ve downloaded a few from wordpress.org but I’m getting a lot of problems any time I try to select one from the Presentation list. * For example, I uploaded the Tarski theme and receive this error: * Fatal error: Class tarskicommentwalker: Cannot inherit from undefined class walker_comment in /web/wordpress/wp-content/themes/tarski/library/classes/comment_walker.php on line 11 * or if I select the Minimalism theme, the page loads, but the content displays as: * Fatal error: Call to undefined function: the_title_attribute() in /web/wordpress/ wp-content/themes/minimalism.1.0.3/minimalism/index.php on line 10 * Every new theme that I install has a similar issue, so I figure it’s not just a broken theme. Is there something wrong on my end, and if so how do I fix it? * [http://www.jamesanzalone.com/wordpress/](http://www.jamesanzalone.com/wordpress/) Viewing 8 replies - 1 through 8 (of 8 total) * [s_ha_dum](https://wordpress.org/support/users/apljdi/) * (@apljdi) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223456) * It looks like a bad install to me. `the_title_attribute()` is a core function. It should be there. I’m not sure about the Tarski error. The ‘undefined class’ might be a WP class, but I don’t have time to dig through the theme right now. * Thread Starter [anzarch](https://wordpress.org/support/users/anzarch/) * (@anzarch) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223457) * I should add, the default themes (Class 1.5 and Default 1.6) seem to work fine but they aren’t suitable to my needs. * Do you think it is a bad install of the theme or of WordPress in general? I can reinstall it if I need to. * [s_ha_dum](https://wordpress.org/support/users/apljdi/) * (@apljdi) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223458) * Like I said, [the_title_attribute()](http://codex.wordpress.org/Template_Tags/the_title_attribute) should be there. Since it seems to be missing the implication is that the WP install is bad. The function does show up in Default 1.6 though, but only on the archives page. You could load that theme and browse to the archives and see whether you get an error. * Thread Starter [anzarch](https://wordpress.org/support/users/anzarch/) * (@anzarch) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223461) * It looks okay when I do that, I don’t see the error in the archives. * [s_ha_dum](https://wordpress.org/support/users/apljdi/) * (@apljdi) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223464) * Paste `&after='); ?>` into your theme’s index.php– the one that is working right now. * Thread Starter [anzarch](https://wordpress.org/support/users/anzarch/) * (@anzarch) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223552) * It didn’t like that, either. It keeps giving the same error, except the formatting appears different (large or small font) and it identifies the line into which I pasted that code as the line in which there is an error. * [s_ha_dum](https://wordpress.org/support/users/apljdi/) * (@apljdi) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223554) * If you get the same error about an undefined functions then that supports the idea that you have a bad install. Files were not uploaded or files are corrupt or permissions are set badly. Do you have FTP access to the site? If so, try [re-uploading everything manually](http://codex.wordpress.org/Upgrading_WordPress_Extended). * Thread Starter [anzarch](https://wordpress.org/support/users/anzarch/) * (@anzarch) * [16 years, 6 months ago](https://wordpress.org/support/topic/theme-installation-errors/#post-1223572) * I think this must be the problem. I will try to reinstall. When I try to install a widget that I downloaded from wordpress, it says it is unable to activate due to a fatal error. Every add-on that I try to put in seems to have an issue, so a reupload will hopefully clear out any bad data that is in there. * I appreciate your help today! I’ll come back if I still have issues after my reinstallation.
