During adding new product I receive the following issue

[2024-07-24 22:26:08] request.CRITICAL: Uncaught PHP Exception Error: "Call to a member function getAdminLink() on null" at /var/www/html/var/cache/prod/smarty/compile/theme_fashion5/b2/3e/ab/b23eab283e66552052cd6c0dfa61116be552ec10_0.file.addtab.tpl.php line 59 {"exception":"[object] (Error(code: 0): Call to a member function getAdminLink() on null at /var/www/html/var/cache/prod/smarty/compile/theme_fashion5/b2/3e/ab/b23eab283e66552052cd6c0dfa61116be552ec10_0.file.addtab.tpl.php:59)"} []

Same issue exists in single product page

PrestaShop: 8.1.7

PHP: 8.1.2

Theme: Fashion 5

Issue didnt exist until I switched theme to fashion5

Ahhh, I don't want to do that.

I investigated it a bit and it looks like the issue is in this module `Modulefieldtsizeguide` delivered by FieldThemes (I think).
So maybe you can fix this and release a new version of the template?

<div id="Modulefieldtsizeguide">
    <h3>{l s='Add or modify customizable properties' mod='fieldsizechart'}</h3>

    {if isset($display_common_field) && $display_common_field}
        <div class="alert alert-info">{l s='Warning, if you change the value of fields with an orange bullet %s, the value will be changed for all other shops for this product'  mod='fieldsizechart' sprintf=$bullet_common_field}</div>
    {/if}
    <div class="form-group">
        <label class="form-control-label" for="id_fieldsizechart">{l s='Select from created guides' mod='fieldsizechart'}</label>
        <div class="row">
        <div class="col-lg-6 col-xs-12">
            <select name="id_fieldsizechart" id="id_fieldsizechart" class="sizecharts_select" data-toggle="select2">
                <option value="0">- {l s='Choose (optional)' mod='fieldsizechart'} -</option>
                {if isset($guides)}
                    {foreach from=$guides item=guide}
                        <option value="{$guide.id_guide}" {if isset($selectedGuide) && ($guide.id_guide == $selectedGuide)}selected="selected"{/if}>{$guide.title}</option>
                    {/foreach}
                {/if}
            </select>
        </div>
            <div class="col-lg-1 col-xs-1">{l s='Or'  mod='fieldsizechart'}</div>
        <div class="col-lg-5 col-xs-11">
            <a class="btn btn-link bt-icon confirm_leave" target="_blank" style="margin-bottom:0" href="{$link->getAdminLink('AdminModules')}&configure=fieldsizechart&addGuide=1">
                <i class="material-icons"></i> {l s='Create new guide' mod='fieldsizechart'} <i class="icon-external-link-sign"></i>
            </a>
        </div>
    </div>
    </div>
</div>
