We have just put out a new version with the Fix and credited you with reporting it in [the changelog](https://wordpress.org/plugins/a3-portfolio/changelog/). * Please try the install with the new version 1.0.2. and if you would not mind letting me know here if it works ok for you with the new version. * Thank you – Steve * Thread Starter [jmdev](https://wordpress.org/support/users/jmdev/) * (@jmdev) * [11 years, 7 months ago](https://wordpress.org/support/topic/error-trying-to-activate-plugin-1/#post-5654665) * That did work and the plugin was able to activate it. * I had a couple problems: - One with the permalinks in the portfolio items (they were 404ing) that was resolved after updating the permalinks so you’re probably missing a flush_rewrite_rules(); during the activation. - Another one in the portfolio page, when I click in one of the porfolio items in the portfolio page it would give a javascript error as follows: - ``` Uncaught TypeError: undefined is not a functiona3.portfolio.min.js?ver=1.0.0:1 (anonymous function) jquery.js?ver=1.11.1:2 m.Callbacks.jjquery.js?ver=1.11.1:2 m.Callbacks.k.fireWithjquery.js?ver=1.11.1:2 m.extend.readyjquery.js?ver=1.11.1:2 J ``` - This error went away once I installed the a3 Portfolio Isotope Add-on. * Thanks for the quick fix and feedback! * Plugin Author [Steve Truman](https://wordpress.org/support/users/a3rev/) * (@a3rev) * [11 years, 7 months ago](https://wordpress.org/support/topic/error-trying-to-activate-plugin-1/#post-5654678) * **Hello jmdev** * Thanks for the feedback * Re this: * _“One with the permalinks in the portfolio items (they were 404ing) that was resolved after updating the permalinks so you’re probably missing a flush\_rewrite\ _rules(); during the activation.”_ * The plugin has the flush rewrite on activation function for when first install– we did not miss it – this is it * ``` if ( get_option('a3_portfolio_just_installed') == 'yes' ) { flush_rewrite_rules(); } ``` * jmdev I do not know with that code in the plugin why you would have had that issue. Today on our local we did a fresh install of WordPress version 4.1 using the default twenty Fifteen theme – installed a3 Portfolios and the flush rewrite function worked perfectly. So I just don’t know what happen on your site as we cannot replicate it. * re this: * _“Another one in the portfolio page, when I click in one of the porfolio items in the portfolio page it would give a javascript error as follows:”_ * jmdev – where did you see that? Where you using a debug tool to see it or did it show on the site? Was it a Chrome DE BUGGER tool? * Again we have tested it on both the clean install and on existing installs and cannot see that Notice using * WP_DEBUG return php error code which we always have on when doing any work * and also tested with Browser JS inspector for debug javascript, style and html * But the Uncaught TypeError notice that you posted gives us some clues – and if you can let me know the DE BUG tool that you where that show that Uncaught TypeError any other info that you think might be relevant – we can have another crack at it. * Thank you for your testing and feedback – it is most useful and appreciated. * Steve * Thread Starter [jmdev](https://wordpress.org/support/users/jmdev/) * (@jmdev) * [11 years, 7 months ago](https://wordpress.org/support/topic/error-trying-to-activate-plugin-1/#post-5654689) * Thanks for your response. * > The plugin has the flush rewrite on activation function for when first install– > we did not miss it – this is it > ``` > if ( get_option('a3_portfolio_just_installed') == 'yes' ) { > flush_rewrite_rules(); > } > ``` > * It could be a problem while updating from the previous version, I haven’t tried to re-install it so if it is working for you right out the bat it should be fine as of now. * > “Another one in the portfolio page, when I click in one of the porfolio items > in the portfolio page it would give a javascript error as follows:” > jmdev – where did you see that?

Was it a Chrome DE BUGGER tool? * I was using the Google Chrome console, this error showed up before installing the “Portfolio Isotope Addon” * I currently do not have any problems with the Plugin, the only thing that bugs me is that after selecting show gallery under that only shows in the individual portfolio pages, it does not show like that in the actual “all” portfolios page, they just show as default ignoring these settings. * Thank you for your support! your portfolio rocks * Plugin Author [Steve Truman](https://wordpress.org/support/users/a3rev/) * (@a3rev) * [11 years, 6 months ago](https://wordpress.org/support/topic/error-trying-to-activate-plugin-1/#post-5654706) * Hello jmdev, * If this is still an issue for you * “_I currently do not have any problems with the Plugin, the only thing that bugs me is that after selecting show gallery under that only shows in the individual portfolio pages, it does not show like that in the actual “all” portfolios page, they just show as default ignoring these settings._“ * Can you please mark this topic of yours as resolved and post a new topic about that issue. Much easier for others to follow if each topic is about a Single issue. * If it is not something that you require help with that is great – could you please, Mark this topic as resolved. * re this: “_Thank you for your support! your portfolio rocks_” * Thank you – if you would give the plugin a 5 star [rating and a review](https://wordpress.org/support/view/plugin-reviews/a3-portfolio) Good reviews rank plugins higher in the WordPress search engine and make it easier for plugins to be found by others. * Steve * Thread Starter [jmdev](https://wordpress.org/support/users/jmdev/) * (@jmdev) * [11 years, 6 months ago](https://wordpress.org/support/topic/error-trying-to-activate-plugin-1/#post-5654712) * Thanks for fixing this.
