Firstly, please go to folder: components/com_rsgallery2/templates/ja_semantic/html and then open file gallery.php. At line 35th you will see
<blockquote>
<li><div class=”rsg2-mygalleries-links”><a href=”<?php echo sefRelToAbs(“index.php?option=com_rsgallery2&page=my_galleries&Itemid=$Itemid”);
?>”>My Galleries</a></div></li>
</blockquote>
Change this text will result in toolbar text.
Next, please go to administrator/components/com_rsgallery2/language, open file english.php
At line 71, you will see:
<blockquote>DEFINE(“_RSGALLERY_MY_GALLERIES”, “My galleries”);</blockquote>
Change this one will result in My Galleries title
Hope this help 🙂
